Gear pump solutions for cannabis industry

WITTE gear pumps for the cannabis industry

We bring our success, our wealth of experience and our know-how to the cannabis industry. The requirement to pump viscous and sticky cannabis residue out of vacuum is not a simple task. However, our CHEM design handles this requirement with ease. Feed pump and distillate pump requirements also fit our CHEM design giving you one pump to provide a pumping solution in your distillation process.

More than 600 pumps are reliable running in a wide range of cannabis applications at US customer plants.

Well suited for:

  • Feeding

  • Metering

  • Residue

  • Distillate

CHEM SP series



Metering systems

Gear pumps are very suitable for exact volumetric dosing with high repeat accuracy. In combination with a mass flow meter, a self-regulating, absolutely precise delivery unit is created. The mass flow meter can be programmed via various interfaces. Once defined, the mass flow meter immediately transmits the smallest changes in the flow rate to the connected drive unit and regulates them so that the volume flow always remains within the tolerance range.

CHEM gear pumps provide the highest level of corrosion resistance with a 316Ti stainless steel housing as standard. An optional integral heating jacket provides the best heat transfer to insure the optimum temperature control.

A wide range of bearing material options offer many self-lubricating choices. These materials help to protect the pump from damage during operation with a starved inlet condition or during cleaning with low viscosity fluid offering poor lubrication characteristics.

Years of proven experience in wide range of distillation processes gives our CHEM pump and our customers an edge against the competition.
