That pharmaceuticals place high demands on their production is hardly surprising. The end-product must be always safe and effective, and waste of precious API 's must be avoided wherever possible.
For example, during production in the pharmaceutical industry, metering pumps are used to dose additives very accurately. These pumps must meet high standards. This is vital to ensure that drug production is safe and effective. Gear pumps are then a logical choice.
One of the advantages of gear pumps is their precision, which is very important for the quality of the final product. This is because the amount of liquid pumped can be controlled and adjusted to the specific requirements of a production process. Wasting expensive ingredients is therefore a thing of the past. Moreover, gear pumps are characterised by continuous, pulsation-free dosing and low shear stress. Two more important contributions to your quality!
As gear pumps are configured specifically for the application, they are highly reliable and durable. The high-quality and possibly polished (Ra < 0.8) materials are resistant to corrosion and wear. This makes them suitable for use in demanding environments, such as clean rooms.
SIP gear pump, hygienic class H3. Sterilisation with steam up to 135°C.
Due to the chemical character of additives, it is often necessary for pumps to be leak-proof. Magnetically coupled gear pumps are hermetically sealed. The shaft seals have given way to a magnetic bushing with static seals that hermetically seal the pump. This way, no leakage can occur!
To meet the GMP guidelines to which pharma must conform, gear pumps are available that are either SIP- or CIP-cleanable. Designed to meet the highest hygiene and quality requirements, they can be thoroughly cleaned without dismantling.

Precise dosing means measuring the flow of liquid and adding or injecting it into a main pipe or pressure pipe in a controlled manner. The pump is controlled, in a so-called "closed-loop control", via a flow meter. The accurate dosing of liquids is becoming increasingly important in modern chemical processes. Chemical companies are achieving increasing success with the production of specialty chemicals and specialty polymers. To produce these products, dosing additives is often essential. Additives add special properties and/or are necessary for an efficient reaction.
Gear pumps which are characterized by high volumetric efficiency (due to their small clearances), are very suitable for dosing applications. Even for low viscous products such as solvents, alcohol or liquefied gas, gear pumps can be used for accurate and pulsation-free dosing.
MAAG dosing pump type dosix with a 3-piece design for easy maintenance
Gear pumps are modular in construction and can therefore be adapted to the specific properties of the liquid to be pumped. Ideal for the chemical industry because the right materials for the pump housing and the internal parts can be selected for each application.
Thanks to this modular construction, the pump materials are not only optimally matched to the chemical properties of the dosed product, but also adapted to the typical process data such as viscosity, operating temperature.
In this way, the pumps are assembled for the intended purpose resulting in a maintenance-friendly and reliable dosing solution resulting in a reliable and accurate process!
Since Suurmond has the HNPM micro gear pumps in its portfolio, in addition to the usual volume flows, it is also possible to realize micro dosing. We are talking about volume flows from 1 microliter per hour!

At a time when shortages in raw materials and materials predominate, delivery times are increasing and the call for sustainable solutions is becoming increasingly emphatic, the choice for a reliable process is more important than ever.
Pumps are an essential part of a process in the process industry, the dynamic part of the installation. That one then opts for a high-quality pump seems a foregone conclusion. Although this may not always be the case. Sometimes one opts for a cheaper solution, which may seem suitable for the present application, but the question of downtime remains. This could be a conscious choice. However, in the current market this can be very disadvantageous, as new pumps are not immediately available due to long delivery times. Stagnation of a production line becomes a risk.
Gear pumps are specifically configured for the application and are therefore reliable. Especially in these times of increasing delivery times, an investment in quality products benefits your operational reliability!

SUURMOND pump unit with a MAAG gear pump
In the process industry there is a wide choice of types of pumps. Depending on the process for which the pump is used, the selection is limited. When a pump is used for dosing additives, for example, or for pumping water, the choice will quickly fall to gear pumps or centrifugal pumps respectively.
Centrifugal pumps are traditionally driven at speed. To achieve the desired volume flow, the pressure line is pinched. This is best compared to a garden hose that is connected to the tap, where the tap is fully opened and the hose is then pinched so that only a small stream of water comes out. This creates a higher pressure in the pipe that would not actually be necessary if the tap were to be opened only a little. At that moment, the pressure (and therefore the problem) is moved to the tap.
In fact, a lot of energy is used to build up a pressure, which is not necessary for a small stream. In this way, a lot of energy is wasted during the life of the pump over many years, because centrifugal pumps often have large installed capacities. 100 - 350 kW is not unusual. There's a lot to save here.
SUURMOND pump unit with a GATHER magnetically coupled gear pump
The speed of gear pumps is often controlled via frequency conversion of the e-motor. The speed of the gear pumps is adjusted with a flow meter or a "load cell" and a closed-loop control in such a way that the pump delivers the desired volume flow. Here, dosing accuracies of 0.1 ... 5% can be achieved. As a result, no more pressure is built up than necessary and much more efficient and energy-efficient pumping can be done.
The gear pumps that Suurmond supplies all have relatively small installed capacities. These typically vary between 0.2 kW and 18.5 kW! In short: the gear pump solution offers significant energy savings over centrifugal pumps.
Where centrifugal pumps often have large installed capacities, gear pumps are all very effective and efficient! Do you want to limit your CO2 emissions and save on energy costs? Then gear pumps are the best choice.
Example of a pump unit with an HNMP micro annular gear pump
This new MAAG pump series, called “FQ” – ‘quick cleaning’ version, is being released for the production facilities with a constant need to clean and wash the transfer line at the end of each production batch, use different colours, use different additives etc. The pump can be disassembled quickly without needing to dismantle the drive shaft from the drive motor and the seal.
The FQ can be disassembled quickly without needing to dismantle the drive shaft from the drive motor and the seal.
This feature can be applied on the existing pump series - CX, TX, FX, DX by using the FQ kit or the pump can be selected as an FQ model itself.
The great benefit of the FQ is that it can change the production and maintenance style of the customers without compromising on the desired operating characteristics.
The FQ kit provides high flexibility and functionality with easy maintenance and part replacement possibilities.
To enable a varied range of process fluids and flow rates, the seal flange can accommodate different pump sizes!
Moreover, to enable a varied range of process fluids and flow rates, the seal flange can accommodate different pump sizes!
For example, the DX 20 can be converted to DX 20/10 or 20/5 and FX 22 can be converted to FX 22/14 or FX 22/8.
In this way, the drive configuration and seal flange can be retained and there can be a possibility to have variations in flow rate depending on the size of the pump that will be installed.
The FQ pump is currently available for the following sizes:
Since the FQ version is unique, the feature is patent protected by MAAG.
Another innovative and smart extension of our industrial pump portfolio!
Maag Pump Systems, a world leading manufacturer of metering gear-pumps, have developed a new range of small gear-pumps for the chemical industry: the pump types flexinox™ (FX) and dosix™ (DX). The driver to develop this new range was to make a chemical pump range with a wider flow rate and reduced costs and increased benefits for the users.
The flexinox™ (FX) and dosix™ (DX) pumps will eventually replace the cinox® & therminox® pumps in the sizes 22, 28, 36 & 45. Other pump sizes remain available.
The internal parts of the flexinox™ are identical to those of the cinox® & therminox® pumps, so spare parts are unaffected by this new development.
MAAG Flexinox 3-piece gear pump allows for easy servicing
The new gear pumps will be much easier to service due to a 3-piece design for the housing. This means that the housing is separate to the front cover allowing for easier removal of the bearings. This was always a challenge with the older cinox® & therminox® pumps.
The new dosix™ pumps have smaller displacement volumes (lower flow rates) than the traditional cinox® & therminox® pumps. The DX pumps are available in sizes 14 and 20 with a smaller pump still in development. These new DX pumps are specially designed for accurate dosing applications and available with modified gears for higher volumetric efficiency in case of low viscosities at high differential pressure.

New MAAG industrial gear pumps for precise dosing and conveyance. For industrial applications the processed medias vary widely from corrosive and abrasive media, to applications with high (differential) pressures, high viscosities, and high temperatures. With the new MAAG innovations, pump types dosixTM and flexinoxTM , Suurmond further extends her portfolio and can herewith satisfy the demand for precise dosing and conveying units even better for a wide range of diversified media.
Due to the chemical properties of the conveyed media, the quality requirements for industrial applications are very stringent and diversified. Thanks to their chemical resistance the MAAG dosixTM and MAAG flexinoxTM gear pumps are used for different chemicals involving highly pure, corrosive, viscous or very hot media, e.g. acids, solvents, molten sulphur, and flavours or fragrances but also for food and pharma processes.
The housing cover of both MAAG dosixTM and MAAG flexinoxTM consists of a three-piece configuration that facilitates maintenance and the replacement of internal parts, i.e. gears and bearings.
MAAG dosing pump type dosix with a 3-piece design for easy maintenance
The MAAG dosixTM is corrosion resistant and electrically heatable especially designed for small throughputs. The superior dosing precision of the pump makes it an ideal solution for applications such as flavours and fragrances that require the accurate dosing of low viscosity scent and aroma components. The new dosixTM is available in five different sizes.
The MAAG flexinoxTM gear pumps are also corrosion resistant and can be heated, either electrically or by fluid. The flow rates are higher compared to the dosixTM and the application range is extended to resins and various plastics, e.g. precursors of carbon fibres. The new MAAG flexinoxTM is available in four different sizes.
To enable a varied range of process fluids and flow rates, the seal flange can accommodate different pump sizes!
