Chem-Tech Series 100 Mechanical Diaphragm Pump Repair Kit (KOP Kit)

The Chem-Tech Series 100 Mechanical Diaphragm Pump Repair Kit is a complete OEM pump repair kit designed to rebuild and restore Chem-Tech Series 100 chemical metering pumps used in water treatment, chlorination, and industrial chemical feed systems.

This KOP (Keep-On-Pumping) repair set replaces all critical wear components in one service interval, helping eliminate leaks, restore dosing accuracy, and extend the service life of mechanical diaphragm chemical feed pumps operating under continuous duty conditions.

If your Chem-Tech Series 100 diaphragm pump is losing output, leaking, or showing inconsistent chemical feed, this diaphragm pump repair kit provides a reliable, manufacturer-approved solution.

What This Chem-Tech Series 100 Pump Repair Kit Is Designed For

This product is a complete chemical metering pump repair kit, not a partial replacement or diaphragm-only service item.

It is specifically used to:

• Rebuild worn Chem-Tech Series 100 mechanical diaphragm pumps

• Replace deteriorated diaphragms, valves, seals, and pump head components

• Restore consistent flow and pressure in chemical feed systems

• Prevent unplanned downtime caused by diaphragm or valve failure

This KOP kit is commonly installed during scheduled preventive maintenance or when pump performance begins to degrade.

Materials & Technical Specifications

• Product Type: Mechanical diaphragm pump repair kit

• Brand Compatibility: Chem-Tech Series 100

• Manufacturer: Pulsafeeder

• Pump Head Material: PVC

• Diaphragm Material: PTFE-faced

• Seal Material: CSPE

• Connection Size: 3/8" suction and discharge

• Application Type: Chemical metering & feed pumps

All components are designed for chemical resistance and long-term reliability in municipal and industrial dosing environments.

What’s Included in This Diaphragm Pump Repair Kit

Each Chem-Tech Series 100 KOP repair kit includes all primary wear components required for a full pump rebuild:

• PVC pump head assembly

• PTFE-faced mechanical diaphragm

• Suction and discharge valve assemblies

• CSPE seals and O-rings

• Mounting hardware (screws and washers)

This is a complete pump repair set, allowing technicians to service the pump without sourcing individual components separately.

Compatibility & Fitment

This Chem-Tech diaphragm pump repair kit is compatible with:

• Chem-Tech Series 100 mechanical diaphragm pumps

• Models with 3/8" suction and discharge connections

• Pump model numbers ending in -AAACXXX

This repair kit is intended for standard (non-degassing) Series 100 pumps. Degassing Series 100 models require a different repair kit designed for off-gassing chemical applications.

Why Use a Complete KOP Repair Kit Instead of Replacing the Diaphragm Only

Replacing only the diaphragm in a chemical metering pump often leads to repeated failures when valves, seals, or the pump head are already worn.

Using a complete Chem-Tech KOP pump repair kit helps:

• Restore original metering accuracy

• Reduce the risk of leaks and pressure loss

• Improve valve sealing and flow stability

• Extend overall pump service life

• Minimize repeat maintenance and downtime

For mechanical diaphragm pumps in continuous-duty water treatment systems, a full diaphragm pump rebuild kit is the preferred maintenance approach.

Typical Applications

This Chem-Tech pump repair kit is commonly used in:

• Municipal water and wastewater treatment systems

• Sodium hypochlorite injection and chlorination systems

• pH adjustment and chemical conditioning systems

• Industrial process water chemical dosing

• Continuous-duty chemical feed applications

The PTFE diaphragm and chemical-resistant materials make this kit suitable for aggressive treatment chemicals when properly applied.
