Gerotor Chemical Metering Pump P-058

Customer Objective

Working to anticipate emerging market demand, our customer was developing an innovative new line of chemical dispensing equipment. Faced with the task of sourcing a rugged, affordable integrated pump that could meter A and B urethane components for a variety of construction applications, the customer turned to Cascon to develop a pump that would:

• Help to simplify the design of the completed system
• Allow use of a pulley or a gear drive
• Optimize reliability of the shaft seal
• Integrate purging ports to prevent chemical from curing within the pump while the system was shut down

The customer’s president, an industry veteran, envisioned a solution that would also employ a specific pump shaft seal design informed by years of field experience and observation.

Cascon Solution

The Cascon team welcomed the challenge — and the input. Merging our familiarity with the requirements for pumping urethane components and the customer’s insights, we designed a simple gerotor pump solution to draw chemical directly from the tank manifold, creating a simple system that significantly improved high viscosity fluid performance.  We incorporated all the desired features into the design, and implemented a unique set of manufacturing and test steps to insure the necessary metering accuracy — all while staying within the budget established for sale of the machine into the customer’s target market.

Pump Features

• Keyed shaft: Compatible with either pulley or gear drive.
• OEM-compatible inlet porting: Streamlined design allows for porting directly from the customer’s fluid tank manifold.
• Custom seal cavity: Collaboratively designed for optimum performance
• Integrated purge ports: Easy-access ports facilitate grease injection for wetted equipment storage.
