The suction and pressure units are a combination of the proven hp-Pressure units with hp-High capacity suction units to handle more difficult heating oil transfer problems.
The suction units can handle underpressures up to -0.9 bar, which is 9 m geodetic height or even up to 200 m suction pipe length. With the pressure unit, loads that are further away, with observable pipe flow, can be provided in single and two-pipe operation.

Can also be supplied with accumulator control
Remark:
The unit types listed contain pump pairings of the suction and pressure pump, based on the many years of experience with our hp suction units
and their average extraction1).
For the layout for the relevant use case, a precise fine-tuning of the pump pairing (depending on suction height, suction length, pipe cross-section, pipe route on the suction side and the pressure height, pressure pipe length, maximum extraction on the delivery side) must be carried out with the manufacturer.
