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 P71 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.

Warranty
|
There
is a 6 month warranty in accordance with VDMA guidelines. Pump operation
without safety valve as well as any excess in temperature or speed limits
automatically voids the warranty. The safety valve must be regulated in
accordance with the guidelines for liquid spraying units so that the admissible
operating pressure can not be exceeded by more than 10%. |
