Chem-Tech Series 100 Mechanical Diaphragm Pumps: Dependable, Adjustable Flow up to 30 GPD, High Pressure 100 PSI, Chemical Resistant Design

Chem-Tech Series 100 Mechanical Diaphragm Pumps – Dependable, Affordable Dosing Performance

Chem-Tech Series 100 Pumps bring proven, long-term performance to chemical metering applications. Engineered with durable motorized-diaphragm technology, these pumps feature a sealed gearbox and eccentric cam for smooth operation, long life, and consistent output. Ideal for water treatment, industrial processes, agriculture, and more, these pumps offer a simple, effective way to manage chemical dosing with adjustable feed rates and robust construction.

Whether you’re dosing less than 3 GPD or up to 30 GPD at pressures up to 100 PSI, the Chem-Tech Series 100 offers reliability you can count on—day in, day out.

Key Features: Unmatched Efficiency and Control

• Motorized-Diaphragm Technology: Offers quiet, consistent dosing performance with long service life.

• Sealed Gearbox with Eccentric Cam: Delivers smooth, vibration-free operation and reliable chemical feed.

• Flow Rate Adjustability: Simple adjustment knob and locking lever for easy turndown and precise control.

• Durable Construction: Compact, injection-molded housing with clear pump head ensures excellent chemical resistance.

• Wide Operating Range: Flows from <3 GPD (0.47 LPH) up to 30 GPD (4.72 LPH), with pressure handling up to 100 PSI (7 bar).

• Reliable Components: Includes clear PVC head, CSPE (hypalon) seals, ceramic valve balls, and 3/8" suction and discharge connections.

• Guided Quad Check Valve System: Enhances dosing accuracy and minimizes wear.

• Standard Bleed Valve Assembly: Enables faster priming and routine maintenance with ease.

Degassing Version Available – For Off-Gassing Chemicals

If you're metering sodium hypochlorite or other off-gassing fluids, choose the Chem-Tech Series 100 Degassing Version. This specialized model includes a degassing valve system designed to eliminate air bubbles from the pump head—ensuring consistent flow and preventing vapor lock. Ideal for water disinfection and other critical chemical feed tasks.
