Chemical Metering Pumps
Case Study: 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.

Chemical Dispensing System
Chemical Metering Pump
For more than thirty years, original equipment manufacturers have turned to Cascon for reliable, cost-efficient chemical metering pumps vital to the packaging, construction, energy, and other industries. Our team’s extensive experience with urethanes and other highly viscous chemicals gives us the insight and knowledge necessary to specify and produce the right solution for each application, and to anticipate challenges that arise in this demanding industry. Whether we’re engaged to configure an existing Cascon design, or to develop a new pump technology, we can offer a cost-effective solution tailored to your specific needs.
Benefits
- Seamless integration with your OEM system. With a wide variety of interface options, we can work together to optimize your system design.
- Reliable and Durable. We’ve been supplying chemical metering pumps based on Gerotor and IGR technology for decades; their reliability has been proven. We have even developed a proprietary coating process for our cast-iron pump to ensure long pump life and reliability.
- Compact Pump Packaging. Gerotor and IGR pump elements are cylindrical in shape. Our experienced designers can efficiently package this technology in the smallest possible form factor for maximum flexibility in the design of your OEM equipment.
Features
- Displacements from 0.061 to 6.1 in3/rev (1 to 100 cc/rev)
- A wide assortment of shaft configurations
- Fluid interconnect options that include manifold mount, straight thread O-ring ports (SAE J1926), or even pipe thread
- Aluminum or cast-iron housings
- Custom seal cavities
- Circuit pressures to 2,000 psi (133 bar)
- Powdered metal, hardened alloy steel, or stainless-steel pump elements
