MDTC - Sanitary open hopper metering pump

designed to improve intake efficiency on highly viscous media

The MDTC range is the hygienic food grade version of the open hopper metering pump. It is used in a variety of applications in the food, beverage, pharmaceutical, and cosmetic industries to convey low to highly viscous media with low flowability. The pumps meet the highest hygienic requirements; adhering to 3-A Sanitary standards and have FDA approval.

Features and Benefits

Energy and time savings

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

Residue-free cleaning

Residue-free cleaning through Clean-in-Place (CIP) continuous cleaning

Technologies, accessories and options

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.

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.

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.

Base plate

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

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.

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 protects the bearing from contamination/gland leakage.

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.

Open hopper

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

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 pin joint

Open barrel-shaped pin joints that can be cleaned effectively through CIP cleaning.

Stator

In food-grade materials according to FDA, and in compliance with EHEDG directives. Follows pharma regulations according to several USP classes.

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.

Pressure branch

Made of stainless steel, polished inside, glass bead blown outside. Allows effective draining. Connection as standard to DIN, Tri Clamp® or any other known fittings

Shaft sealing

Mechanical seal product flushed and located within the suction area for optimum cleaning.
