STB has developed an intensive program for hand pumps due to ever increasing requirements regarding durability, quality and safety. Our hand pumps are made of stainless steel 1.4404 and FKM (other materials by request). Based on the materials used, it is possible to pump many different substances including water, hydro-glycol mixtures and oils. Thanks to STB’s inhouse development and production, it is possible to provide material certificates and test reports regarding all materials. As a result, we are able to offer and design hand pumps in explosion protection applications. Thus we are the most competent supplier in this field on the market. The main field of application for these pressure booster pumps or replenishment pumps can be found on drilling platforms, production sites, refineries, tank farms or in the chemical industry.

The hand pumps are easy to operate and are equipped with one-way valves.
