Product description

Reliable capacity even at high-pressure

ORLITA MF hydraulic diaphragm metering pumps (MFS 35 to MFS 1400) with a stroke length of 15 to 60 mm provide a capacity ranging from 0 to 14,000 l/h at 450 – 30 bar. A wide range of drive versions is available, including some for use in Zone 1 or Zone 2 areas at risk from explosion with ATEX certification. The ORLITA MF product range is designed to comply with API 675. Its modular construction permits the free combination of drive units, drives and dosing heads, producing a pump for a range of different feed rates and media operating at different working pressures.

Your benefits

Excellent process safety and reliability:

PTFE double diaphragm with integrated diaphragm rupture warning system ensures precise and low-wear operation despite high pressures
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:

The modular construction allows a wide range of uses. In multiple pump systems it is possible to combine up to 6 metering units, even with different pump capacities. In single pumps the drive arrangement may be either vertical or horizontal.

Metering of Fluids in Chemical Production

Incredible versatility: metering pumps in production

There are various types of metering pumps, but what they all have in common is reliability, robustness and thoroughness. That's why all our pumps are in demand in chemical production.

Inhibitor Metering Offshore

For smooth oil production

Our ProMinent metering pumps keep the pipework clear 24 hours a day and protect against corrosion and defects. So the oil can keep flowing.

Onshore Metering in Gas Pump Stations

Safety at the borehole

Flammable methane hydrate at the borehole can be very dangerous. But not with ProMinent metering pumps. By metering fluid into the drilling head, they don't even allow methane hydrate to be produced in the first place.

Downstream Oil Treatment

It's all about the oil

Makro diaphragm metering pumps or even the new Evolution pumps are used for emulsion cracking so that the precious oil is perfectly separated from other substances. The pumps are completely autonomous.

Metering of Fluids

Incredibly simple and efficient metering of chemicals

We transport chemicals with ease in any industrial environment: ProMinent solutions store, transfer and meter substances at rates of 0.1 l/h to 100,000 l/h at a pressure of 2 to 3,000 bar.

MfS 35 (MF2a) – stroke length: 0-20 mm, rod force: 3500 N
MfS 600 (MF5b) – stroke length: 0-40 mm, rod force: 40,000 N
MfS 1400 (MF6a) – stroke length: 0-60 mm, rod force: 60,000 N
Stroke length adjustment range: 0 – 100% in operation and idle
Stroke length adjustment: manually using manual adjustment wheel and scaled display (optionally with electric actuator or control drive)
Metering reproducibility is better than ± 1% within the 10 – 100% stroke length range under defined conditions and with correct installation (API 675)
PTFE multi-layer diaphragm with electrical diaphragm rupture warning/signalling system via a contact
Integrated hydraulic relief and bleed valve
Wetted materials: Stainless steel, special designs are available on request
A wide range of power end versions is available: Three-phase standard AC motors, motors for use in areas at risk from explosion and different flange designs for use in customer-specific motors
Degree of protection: IP 55
Temperature range - 40 °C to + 150 °C
Suction lift up to 8 m
Design in compliance with API 675 among others

Actuation of ORLITA MF, MH, PS, DR

Control drive consisting of an actuator with servo motor and integral servo controller for stroke length adjustment via a standard signal. Standard current input 0/4 – 20 mA, corresponds to stroke length 0 – 100%, switch-over for manual/automatic operation; key switch for stroke adjustment in manual mode, mechanical position display of actual stroke length value output 0/4 – 20 mA for remote display. Control drives can also be designed with bus systems, like HART, PROFIBUS^®, Fieldbus Foundation ...

Variable speed motors with integrated frequency converter (identity code specification V)

Power supply 1 ph 230 V, 50/60 Hz (up to 3 kW). Externally controllable with 0/4 - 20 mA.

The following functions are integrated in the terminal box cover:

Start/stop switch
Switch for manual/external operation
Potentiometer for speed control in manual mode

Speed controllers with frequency converter (identity code specification Z)

The frequency converter is accommodated in an IP 55-rated protective housing with integral control unit and main switch, suitable for max. 0.37/0.75 kW motor capacity.

Externally controllable with 0/4 - 20 mA or 0 - 10 V corresponding to 0 - 50 (60) Hz output frequency.

Integrated control unit with versatile functions, such as switching between external/internal control; frequency input using arrow keys with internal control, multilingual fault message display etc. and motor temperature monitoring (thermistor protection).

The speed controller assembly consists of a frequency converter and a variable-speed motor.
