Achieving Accuracy

After discussing the parameters of the operation, Klaassen was convinced that an E-Series Plastic Air-Operated Double Diaphragm (AODD) Pump from Almatec was the perfect answer for the challenge of dosing the enzyme at a highly accurate rate. Almatec is a product brand of PSG, a Dover company, and Holland Air Pumps is a distributor of Almatec pumps in The Netherlands.

“We chose the Almatec pump because of the dosing capabilities needed, which run a broad perspective from very low to very high,” said Klaassen. “Because it was a new application, we gave the customer a test unit with pulse dampeners for them to try. When they were satisfied with the performance, Technology Unlimited built the skids that would house the pumps that would dose the enzymes for the animal feed.”

The E-Series pump was the ideal choice for the enzyme-dosing application because it features a solid-body design and is constructed of polyethylene (PE), which offers excellent corrosion-resistance. The E-Series pumps, thanks to their PE construction, have been shown to last seven times longer than pumps that are made with polypropylene (PP).

Solid PE also delivers better sealing, higher static weight, smoother operation and better torque retention than other popular materials of construction. For specific applications, E-Series pumps can be constructed of PE, PE conductive, PTFE and PTFE conductive. The diaphragms and valves are also available in different materials.
