Pumps for sealing applications

Fluid Handling

Sealing is used to make a pump's mechanical seal safer in processes where the pump is used for pumping toxic, reactive (oxygen and/or moisture) and volatile substances. The objective of sealing is to make processes safer. In general, this is applied to larger centrifugal pumps that are often equipped with a double mechanical seal. Sealing these mechanical seals requires sealing units. In some cases, the sealing fluid must be forced actively with an additional pump, and/ or under high pressure. This is done by actively pumping (circulating) sealing liquid.

Our solutions for sealing 

Centrifugal pumps are equipped with a pumping ring for circulation of the sealing liquid. Main functions of sealing systems are sealing and cooling. When the pump stops, circulation also stops, risking high temperatures, resulting in possible seal damage or even leakage with all the resulting consequences. 

By applying gear pumps, the circulation of the sealing liquid continues, even when the main pump is stopped.  

For sealing applications, Suurmond offers gear pumps in cast iron, cast steel and stainless steel. At request, conformance with API 676 and suited for the (so-called) API – seal plan (American Petroleum Institute). We also offer ATEX certification. 

Even for sealing systems with pressures up to 325 barg, we have a solution. Pumps with magnetic coupling! 

In addition to gear pumps for circulation, Suurmond designs dedicated sealing units according customer specifications!
