SPECK TRIPLEX Plunger Pumps are suitable for pumping clean water and other non-agressive or abrasive media with a similar specific weight to water.

Prior to pumping any other media, a check must be made to find out whether these pumps , taking pump performance and temperature values into consideration, are at all suitable for pumping the required medium.

Even though SPECK-TRIPLEX P21 pumps run almost pulsation-free, there are cases where a pressure accumulator is necessary. This will depend mainly on the construction of the unit and the conditions under which it is operated. The same effect can also be achieved by using flexible pressure lines. In any case, use of a pulsation damper adds considerably to the life of the seals and bearings. Particular care has to be taken when pumping warm water, making absolutely sure that cavitation can not occur.
