Do the valves suffer from blockages?

The pump non-return valves have been proven to be highly resilient to blockages. The Mallard Bullfrog Valve for example which is commonly used across a range of industries and in both the Diaphragm and Ram Pumps can handle a hard spherical solid of 60mm without blockage.

Can these pumps be run dry?

Both the Ram and Diaphragm Pumps can run dry for short periods without causing damage.

Are the pumps self-priming?

The Ram and Diaphragm Pumps are able to self-prime.

Do the pumps require any surge arrestors (Pulsation dampers)?

Due to the pulsed flow inherent with both Ram and Diaphragm Pumps we would recommend surge arrestors for most applications to help smooth the flow in the pipework, which reduces ‘Water Hammer’. Typically a surge arrestor would be required on both the suction and delivery of the pipework, however there are always exceptions and we are happy to advise.
