Product Description

By keeping track with the market development, we are engaged in providing our clients with excellent quality Electromechanical Dosing Pumps. This dosing pump is used wherever fluids must be dosed into a medium with a highest possible grade of accuracy. Offered dosing pump is developed from premium grade components at par with set norms. The given dosing pump is stringently tested on numerous predefined parameters for delivering a perfect range.

Features:

Pump performance in accordance with API 675
Leak less Pump
Low maintenance & accuracy for longer period
Used for pumping toxic / hazardous chemicals
Can pump wide range of liquid
Built in safety feature

Working Principle:

An Electrical Actuator is a device, which converts electrical energy derived from motor to corresponding mechanical movement which is imparted on final control element
Each Electrical Actuator is provided with Hand wheel with clutch for manual operation in case of power failure. A continuous local mechanical position indicator is provided which shows real time opening/closing of Actuator irrespective of whether Actuator is in manual or electrical mode
These Actuators work with an Input signal of 4-20mA
Normally 4mA output signal corresponds to Fully close i.e. 0% stroke length of pump condition and 20mA corresponds to fully open condition i.e.100% stroke length of pump
A feedback Potentiometer fitted inside the Actuator converts the mechanical movement of
A two wire Position Transmitter PPT 200 converts resistive output of Actuator mounted feedback potentiometer to corresponding 4mA to 20mA current output
A positioner unit which also acts as a comparator, compares input signal of 4mA to 20mA based on process parameters, with feedback signal of (4- 20)mA generated from Actuator mounted PPT 200 and generates open/close relay signal through IC’s which is routed through RC network for
