Pulsafeeder J37440 Hypalon CSPE Valve Seat for Chem-Tech Pumps
Replacement Check Valve Seat for CHEM-TECH Metering Pumps
Pulsafeeder J37440 Hypalon (CSPE) replacement valve seat for compatible Chem-Tech Series 100, 150 and 200 chemical metering pumps and check valve assemblies.
The Pulsafeeder J37440 is a Hypalon (CSPE) replacement valve seat designed for compatible Chem-Tech chemical metering pump check valve assemblies. This component provides a sealing surface for the check valve ball, helping maintain proper fluid-flow control during chemical metering operations.
Pulsafeeder parts documentation identifies J37440 as a Hypalon valve seat for Chem-Tech pump systems. The component is used in compatible liquid-end valve assemblies where the original equipment specifies a CSPE sealing material.

Hypalon CSPE Valve Seat Construction
The J37440 valve seat uses Hypalon (CSPE), an elastomer material used in compatible chemical feed systems. CSPE provides chemical resistance for selected process fluids when used within appropriate operating conditions.
The valve seat forms the contact surface against which the check valve ball closes. Proper sealing helps the check valve control fluid movement through the pump liquid end.
Chem-Tech Pump Applications
Pulsafeeder identifies J37440 in Chem-Tech replacement parts documentation. Distributor parts listings associate this valve seat with compatible Series 100, 150 and 200 mechanical diaphragm metering pump configurations.
Potential applications include:
- Chem-Tech Series 100 chemical metering pumps
- Chem-Tech Series 150 chemical metering pumps
- Chem-Tech Series 200 chemical metering pumps
- Compatible Series 100D and 150D configurations
- Chemical metering pump check valve maintenance
- Replacement of worn liquid-end valve seats
Check Valve Sealing Performance
The Pulsafeeder J37440 Hypalon valve seat helps provide a sealing interface for the check valve ball. Check valves are important in chemical metering systems because they support controlled fluid movement through the pump during suction and discharge strokes.
A worn or chemically damaged valve seat may contribute to leakage through the check valve, reduced priming performance or inconsistent chemical delivery.
Maintenance and Replacement
Inspect valve seats during scheduled pump maintenance for cracking, deformation, swelling, surface wear and chemical deterioration.
Replacing damaged valve seats with correctly specified components can help restore the intended check valve sealing arrangement and support reliable pump operation.
Compatibility and Installation
Before ordering the Pulsafeeder J37440, verify the original valve seat part number, pump series, liquid-end configuration and chemical compatibility.
CSPE is not suitable for every chemical application. Confirm compatibility with the process fluid, concentration and temperature before installation.
Follow the manufacturer maintenance instructions when servicing the chemical metering pump check valve assembly.
