Pressure booster pump
The PFT pressure booster pump is used predominantly as a high-
pressure pump for intermediate connection at the mortar mixer when
the water pressure is too low. It can also be used as a primer pump for
drawing liquids from containers, for emptying small tanks and ponds,
for pumping water out of cellars and for irrigation.
The water supply is automatically ensured from a water tank by the
PFT pressure booster pump for the constant water supply to the PFT
machine engineering.
A flow pressure of at least 2.5 bar with the machine in operation on
the construction side is guaranteed by means of suction from the
water reservoir.
