2300 Series

The 2300 Series mechanically actuated diaphragm metering pump is a compact, modular, state-of-the-art design. Simplex and duplex models are available. The rugged design makes this pump ideal for most municipal or industrial water treatment chemical pplications.

Instruction Manual

Spec Sheet

This pump has a metering head designed with a separation chamber behind the diaphragm which will protect the body of the pump should the diaphragm rupture or crack due to wear. Any leakage will drain harmlessly back to the tank or an alternate location. Escaping leakage may be detected by a probe that can be used to shut off pump or send an alarm.

Nine different models are available, offering maximum capacities from 17 to 310 gph and a maximum pressure rating of 150 psig. The drive consists of a single stage reduction worm gear. The drive is lubricated for long life and includes a 120 VAC single phase or 230/460 VAC 3-phase TE or XP motor. The stroke length may be either manually or automatically adjusted from 0-100%. The 2300 Series is designed with low stroking speeds for long term reliability.

The 2300 Series is supplied with PP and 316 Stainless Steel wetted ends. All diaphragm are PTFE coated EPDM for severe chemical duty applications. Check valves are double ball type on both the suction and discharge side. The spring loaded single ball design is available for Models 2370-2390 and are otherwise optional for metering chemicals with higher viscosities. Tubing and NPT pipe connections are standard.

• A micrometer adjustment allows for in-motion capacity adjustment of 0-100%
• Power supply - single phase or 3-phase TE or XP motor.
• All internal mechanics are oil lubricated
• Electronic capacity adjustment (ECA) will control pump capacity in response to a 4-20 mA signal.
• Belt drive system allows for extended range of speeds to meet changing capacity requirements due to seasonality, etc.
• Automatic AC or DC motor speed control by analog input signal
• Double diaphragm system protects environment and pump components in case of diaphragm rupture. Also provides continuation of critical process until maintenance shutdown is scheduled.
• Leak detection system provides alarm signal in case of diaphragm rupture.
• Spring loaded single ball check valves
• Injection nozzles and foot valves
• Municipal water treatment
• Industrial chemical applications
