MDC - Sanitary metering pump

For metering applications requiring FDA and 3-A Sanitary-Standards

SEEPEX MDC pumps are a range of hygienic metering pumps used in a variety of applications in the food, beverage, pharmaceutical and cosmetic industries to convey low to viscous media as well as shear-sensitive media. The pumps meet the highest hygienic requirements; adhering to 3-A Sanitary standards and have FDA approval.

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

Residue-free cleaning

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

Exact dosing

Additives can be precisely metered without loss. This saves costs for cost-intensive additives

Technologies, accessories and options

Seal barrier system

This unit protects the shaft sealing by selectively supplying barrier liquid. Also available with flow meter on request.

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.

Multiple-acting mechanical seal

Mechanical seals arranged in a row. Available in "back-to-back", "face-to-face" or "tandem" sequence.

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.

Pressure branch

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

Rotor

Wear resistant and corrosion-proof materials.

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

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

Open pin joint

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

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.

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.

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.

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.
