Laboratory Pumps – PEEK vs Stainless Steel

There are four options for the choice of head material for your laboratory pumps. It is important that you choose the correct option for your application. Typically the most important factor is the chemical compatibility. PEEK (polyetheretherketone) is an engineering plastic. It is hard and will be suitable for applications up to around 6000psi. It … Continued

Laboratory Pumps – What are piston pumps?

Piston laboratory pumps are positive displacement pumps. They use a reciprocating piston and check valves to give a constant flow. Typical laboratory pumps have heads as shown below. At the front of the head there are two check valves (these have the red balls). These allow the fluid to only flow in one direction (in … Continued
