DESIGNED TO IMPROVE INTAKE EFFICIENCY ON HIGHLY VISCOUS MEDIA
SEEPEX MDT range pumps are used to convey highly viscous media such as peanut butter, molasses, resins, and other media with low flowability. The open hopper on the pump directs media to the auger feed screw on the coupling rod which feeds the media into the rotor and stator.
Compression zone increases capacity of conveying chamber resulting in process time and energy savings
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

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

Closed pin joint
With or without joint sleeve, which protects the grease-filled joints from penetration of the pumped liquid.
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.
Open hopper
Rectangular feed hopper with conveying screw for pumping higly visous products.
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
A corrosion resistant design, optionally made of stainless steel, connects the pump and drive and secures the assembly to the base plate or skid.
Plug-In shaft connection
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.
Base plate
Tailor-made selection of base plates. The base plates can be easily combined with different drives from all major manufacturers.
Drive
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.
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.
Dry-running protection device (TSE)
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.
Standard Gland Packing
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.
Single-acting mechanical seal
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.
