Pulsafeeder 28800 Clear CHEM-TECH Series 100/150 Pump Head

The Pulsafeeder 28800 is a clear CHEM-TECH chemical metering pump head used in compatible Series 100/150 liquid-end assemblies. The original Pulsafeeder service manual identifies part 28800 as a pump head with SAN-acrylic construction, while replacement-part suppliers also describe it as a clear PVC pump head.

This component forms part of the pump liquid end, where chemical solution is displaced during normal diaphragm pump operation. It is a pump head component rather than a complete metering pump.

Function of the Pump Head

The pump head provides the fluid chamber in a compatible diaphragm metering pump. Together with the diaphragm and suction and discharge valves, it supports the controlled movement of chemical solution through the liquid end.

Clear Pump Head Design

The clear construction provides visibility of the liquid-end chamber. This can assist visual inspection during servicing, although pump operation and troubleshooting must still follow the manufacturer instructions.

CHEM-TECH Series 100/150 Application

Pulsafeeder identifies part 28800 in the Series 100/150 wet-end assembly documentation. Verify the original pump model, head material and associated components before ordering because other CHEM-TECH configurations use different pump head materials.

Typical Applications

• CHEM-TECH chemical metering pump maintenance
• Replacement of damaged pump heads
• Water treatment chemical feed equipment
• Industrial liquid-end servicing
• Repair of compatible diaphragm metering pumps

Maintenance Considerations

Inspect the original head for cracking, chemical attack, leakage and damaged sealing surfaces. Check the diaphragm, valve components and mounting hardware when performing liquid-end maintenance.

Installation Guidelines

Disconnect electrical power, isolate the chemical supply and release system pressure before removing the pump head. Follow the Pulsafeeder maintenance manual for assembly, sealing and fastener tightening procedures.

Ordering Information

Order Pulsafeeder 28800 for the clear CHEM-TECH pump head. Confirm the material designation and pump compatibility with the supplier before installation.
