Milton Roy GM0002-0500 series metering pump- Hydraulic end
Mechanical driven diaphragm, without diaphragm protection plate on the material side, making it easy for materials to pass through.
Various pump head materials such as PVC, PVDE, 316SS, high viscosity, and slurry are suitable for various materials.
● Self cleaning one-way valve structure.

Milton Roy GM0002-0500 series metering pump- Drive end
Variable eccentric mechanism adjustment ensures smooth changes in flow pulsation.
Enhanced structural design, suitable for harsh operating environments.
Wear resistant ball bearings make work more stable.
Oil bath lubrication ensures long working life of the driving components.
The flow can be adjusted in both shutdown and operation states, and the adjustment methods can be manual, electric, or variable frequency.

Milton Roy GM0002-0500 series metering pump—control mode
Electric stroke controller, receives external control signals and adjusts stroke length.
Power supply: 220V -50Hz - single-phase
● Input signal: 4-20mA analog signal
Output signal: 4-20mA/1-5V analog signal, for recording, display, and control system use.
Variable frequency controller, accepts external control signals, adjusts stroke speed
Power supply: 220V-50Hz single-phase/380V-50Hz three-phase
● Input signal: 4-20mA analog signal
Motor controller, controls the three-phase motor in an "on/off" manner and adjusts the output flow rate
Power supply: 200-240V/50/60Hz/single-phase
Control mode: Acceptable 4-20mA analog signal, external pulse signal or manual adjustment

Milton Roy GM0002-0500 series metering pump- Automatic control mode selection
The electric stroke controller receives external control signals to adjust the stroke length of the metering pump, thereby changing the output flow rate of the metering pump.
GM series metering pumps choose ST type. Choose ECC type for GB series metering pumps.
Variable frequency controller: accepts external control signals, adjusts the stroke frequency of the metering pump, and thus changes the output flow rate of the metering pump.
Power supply: 220V/50HZ unidirectional
380V/50HZ three-phase
Control signal: 4~20mA
Motor Controller (VARIPULSE):
Only used for GM series metering pumps, used to control three-phase motors, change stroke frequency, and adjust the output flow of the metering pump.
