MD - METERING PUMP FOR PRECISE METERING AND DOSING

DESIGNED WITH THREADED CONNECTIONS FOR GENERAL METERING APPLICATIONS

MD Range progressive cavity pumps are used in virtually all industries for metering and dosing precise quantities. They are particularly good for minimal pulsation conveyance of thin to viscous fluids, as well as corrosive media containing solids.

Conveying Capacity
0.06–1,000 l/h
0.053–264 US gph
Pressure
≤ 24 bar
≤ 350 psi

Features and Benefits

Economical

Reduced costs due to inexpensive rotating unit

No vapor locking

Cavity design allows for conveyance of liquids, solids, and gases

Ease of operation

Valveless flow control for ease of operation

Performance efficiency

Low slip (internal back flow) provides performance efficiency and less wear on components

Easy maintenance

Simple and predictive maintenance due to minimal components

Durable

High corrosion resistance due to the variety of components made of Hastelloy C or Titanium

Exact Dosing

High dosing accuracy (deviation only +/- 1%)

Technologies, accessories and options

  • Technology
  • Accessories
null

  • Pressure branch

    In stainless steel, 1/2" connections to DIN EN ISO 228-1 or NPT.

  • Stator adapter

    In stainless steel, enabling the use of all sizes of rotor/stator giving inter- changeability with only one housing and drive unit.

  • Rotor

    Wear resistant and corrosion-proof materials.

  • Conventional geometry

    With short pitches and a compact design, the conventional geometry produces high pressures.
    null

  • 6L geometry

    With a small rotor diameter and a long pitch, the 6L geometry attains lower surface velocities and extends the service life due to its large sealing line.
    null

  • Tricam geometry

    The rotor with Tricam geometry features a three-helix geometry. This enables it to achieve larger conveying capacities with the same overall length of the pump.
    null

  • Stator

    The seal on both ends is moulded as an integral part of the elastomeric stator. Corrosion of the stator tube is never a problem because the pumped liquid never comes into contact with the metal tube or the bonding adhesive.

  • Suction casing

    In stainless steel, 1" connection to DIN EN ISO 228-1 or NPT, can be rotated in 90° increments, with drain plug, available with gauge or flushing connections.

  • Coupling rod

    With two pin joints with hardened and wear resistant components, easily assembled, grease lubricated and positively sealed with elastomer sleeves and two holding bands.

  • Shaft sealing

    Single-acting mechanical seal, independent of direction of rotation, with quench and supply tank (78 cm / 3 to 4 l) to protect the sliding surface against dry running.

  • Plug-in shaft

    Connects the drive shaft to the joint. With gland packing the plug-in shaft is used as a shaft protection sleeve. Upon request, it is available with wear resistant coating.

  • Lantern

    For connection of pump and drive and to secure the assembly to the baseplate or directly to the foundation.

  • Overpressure Protection

    The pressure gauge switches off the pump as soon as a pre-set pressure is exceeded or not reached and protects the pump from increased wear and tear or piping damage.
