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.
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
- Municipal water treatment
- Industrial chemical
