Sealing technology: Eight different seal versions for different applications Housing: Stainless-steel housing as standard. Lots of special materials such as ceramic or coatings are possible. CHEM series chemical pumps come as standard with stainless-steel components, or there are special versions with coated or ceramic materials. The CHEM series was developed for easy maintenance. Separate pump covers make quick inspection of the interior possible from both sides of the pump. To adjust the axial clearance we use spacers that can be varied depending on the process parameters. There are two...

Metering systems/technology CHEMICALS PHARMACEUTICALS AND COSMETICS POLYMERS Gear pumps are highly suitable for precise volumetric metering with high reproducibility. When used in combination with a mass flow meter and a control system, a self-regulating, absolutely precise pumping unit is created. A wide range of interfaces can be used to program the mass flow meter. Once defined, the mass flow meter instantly forwards even the smallest changes in flow to the connected drive unit and regulates the volumetric flow so that it always stays within the tolerance range. Sample structure of a...

Synchronous magnetic coupling Radial shaft seal ring PRESSURE SUCTION SIDE Each rotating pump has a drive shaft that must be sealed somehow. A wide range of systems and seals can be used for this purpose. Different systems are used depending on the pump type and application area. The selection of seal types is determined by the process parameters. Pressure, temperature and viscosity are crucial factors that affect or limit the seal selection. PRESSURE SUCTION SIDE Single Vacuum mechanical seal (AD), mechanical seal (ED) buffered without pressure Double mechanical seal, Quenched internal...

CHEM magnet (magnetic coupling) CHEMICALS Special situations call for special solutions. Our magnetic coupling is safe, reliable and flexible to use. The result: No wear, maximum life expectancy and increased operational safety. Magnets: We offer a wide range of versions of this seal type. The seal is a combination of a hermetic seal at the pump and a touchless drive. In contrast to conventional magnetic couplings, our version has a separate rotor bearing that transfers only the torque to the drive shaft. There is therefore no additional load on the pump bearings by the weight of the...
