roduct description: 
G series mechanical diaphragm metering pump 

Features: ● Design, smooth pulse, no impact, stroke are adjustable in the static and dynamic conditions 
● many kinds of material and the optional pump head structure, electric stroke controller is optional 
● mechanical drive PTFE diaphragm, the maximum liquid temperature 40 ℃ * 
● manual/automatic stroke adjusting optional, steady state accuracy of plus or minus 2% (10% ~ 100%) Stroke can be adjusted 0 ~ 100% (auto/manual), maximum 4 m water column suction * 
● optional motor controller to realize automatic external signal control, the maximum suction pressure: 20 m water column Motor adjustable frequency 0 ~ 100% (GM pump automatic control mode) 

● optional double diaphragm pump head structure 
● recommended maintenance cycle: 1.0 MPa 4000 h or less ≤0.7MPa 8000h 

Automatic control mode selection • electric stroke controller accept external control signal, adjust the metering pump stroke length, which changes the metering pump output flow. 
GM series metering pump selection ST type.GB series metering pump type selection ECC. 

Frequency conversion controller:Accept external control signal, adjust the metering pump stroke frequency, thus change the metering pump output flow. 
For electricity: 220 v / 50 hz one-way 
380 v / 50 hz three-phase 
Control signal: 4 ~ 20 ma 

Motor controller (VARIPULSE) : Only used for GM series metering pump, used to control the three-phase motor, change the stroke frequency, adjusting the metering pump output flow. 
V - with metering pump one-piece installation 
VR type - with metering pump system installation

VARIPULSE motor controller parameters
For electricity: (+ 10%) / 50 hz single-phase 220 v 
The motor power: 0.09 ~ 0.75 KW Protection grade: IP55 
Ambient temperature: - 20 ~ 40 ℃ Fault indicator: the instructions 
Passive contact output (250 v / 1 a) Control mode 1: analog signal control 
Control input signal is: 4 ~ 20 ma Lose the resistance: resistance of 250 ohms 
Stroke frequency adjust: 0 ~ 144 SPM Control mode 2: potentiometer to adjust manually 
The adjusting range: 6 ~ 144 SPM Control mode: the pulse signal control 
Control input signal: passive contact or open collector
Pulse impact frequency rate: Max. 144 pulse/min (= 1 pulse discharge of a stroke) 
The range of the metering pump: GM0010, GM0050 GM0170 ,GM0240 GM0330
Note: match the metering pump VARIPULSE control must be special sensing probe assembly.Stroke frequency metering pump can be adapted for the 144 SPM VRIPULSE controller.
Warning!Choose this series metering pump applications, recommended in the pump outlet pipe install relief valve on the road. Model coding technical parameter
