High Accuracy Metering
ORLITA MH hydraulic diaphragm metering pumps (MHS 18 to MHS 600) with a stroke length of 15 to 40 mm provide a capacity range of up to 320 l/h at pressures of up to 780 bar. A wide range of power end versions is available, including some 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
Excellent process reliability:
- Metal double diaphragm with integrated diaphragm rupture warning /signalling 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 vent 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
- The modular construction ensures a wide range of uses
- 6 different gear ratios are available
- Power end configuration ideal for installation in any position (vertical or horizontal)
- Temperature range -40 °C to +200 °C
- Customised designs are available on request
