700 bar (10,152.642 psi)


The diaphragm metering pump Orlita® MH has a robust metal diaphragm, which permits precise pump capacities even at very high pressure. The ORLITA® MH has a modular construction and therefore has a versatile range of uses. A range of power end versions are therefore available and drives, power ends and dosing heads can be freely combined.

Reliable capacity even at very high pressure

ORLITA® MH hydraulic diaphragm metering pumps (MHS 18 to MHS 1400) with a stroke length of 15 to 60 mm provide a capacity range of up to 800 l/h at pressures of up to 7 bar. A wide range of power end versions is available for use in areas at risk from explosion with ATEX certification. The Orlita® MH product range is designed to comply with API 675. Its modular construction permits the free combination of drives, power ends and dosing heads, producing a pump for a range of different feed rates and media operating at different working pressures.
Your benefits

Metal double diaphragm with integrated diaphragm rupture warning system ensures precise and low-wear operation even at very high pressure
The product chamber is hermetically separated from the hydraulic part
Integrated hydraulic relief valve and automatic bleed valve for the hydraulic chamber
Wear-free, valveless enforced anti-cavitation of the hydraulic leakage guarantees optimum dosing precision
Cone valves for use as suction and/or discharge valves with minimal wear, good self-cleaning and low pressure loss (NPSHR)

Excellent flexibility:

It is possible to combine up to 6 metering units, even with different pump capacities, in multiple pump systems
