MDT - OPEN HOPPER METERING PUMP

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

Optimized compression between the rotor and stator using wear-resistant and corrosion-resistant materials. A wide range of alloys, coatings and elastomers are available for each.

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

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.

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.

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.

With or without joint sleeve, which protects the grease-filled joints from penetration of the pumped liquid.

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

Rectangular feed hopper with conveying screw for pumping higly visous products.

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.

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.

A corrosion resistant design, optionally made of stainless steel, connects the pump and drive and secures the assembly to the base plate or skid.

For easy dismantling of the pump and drive enabling quick replacement of the rotating parts and shaft seals. The plug-in shaft pin secures the shaft connection to the drive and the splash ring both secures the plug-in shaft pin and protects the bearings from contamination / gland leakage. Easy access to the pump and drive enables quick replacement of the rotating parts and shaft seals.

Tailor-made selection of base plates. The base plates can be easily combined with different drives from all major manufacturers.

Geared motors, variable speed drives or frequency controlled motors of all major manufacturers, directly flanged to the pump without additional couplings or guards. Covers made of stainless steel are available.

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.

TSE monitors the temperature of the rotating stator and shuts down the pump when the limit value is reached to protect the pump from dry running.

Universal seal for hopper and standard pumps for sealing the plug-in shaft and suction casing or feed hopper. Also available with grease or lantern ring to shut off the media flow. Can also be supplied with upstream labyrinth seal and additional flush connection or lubricating device.

Universal standard mechanical seal for dosing, food applications and semi-submersible pumps for sealing the plug-in shaft in the suction casing or the hopper.
