Chemical Diaphragm Dosing Pump for water treatment

1. Safety and Precautions

Avoid temperatures above 0-40。C, or pumps and pipes are directly exposed to direct sunlight using pumps. Be sure to cut off the pump power before maintenance.

When operating the pump or its surrounding environment, be sure to properly wear the protective equipment and equipment recommended by the liquid supplier. Be sure to release the pressure before removing the pipe or repairing the pump.

2. Working principle

EP series electromagnetic metering pump consists of pump head, driver and controller. The drive is an electromagnetic coil. When the controller energizes the coil, the core and connecting rod move forward under the action of electromagnetic force. The forward movement of the diaphragm reduces the pump cavity space and increases the pressure, forcing the fluid in the pump cavity to be discharged through the valve assembly of the outlet pipe. When the current of the coil is cut off, the iron core and the connecting rod are bounced back to the original position by the elastic force of the reset spring, the connecting rod drives the diaphragm back, the space in the pump chamber increases and the pressure drops, and the liquid in the tank is under atmospheric pressure. Through the controller drive the driver's frequent action to complete the liquid is inhaled and spit out.

3. Specifications

Parameters

Attention 1. pump performance is obtained by pumping water at ambient temperature at rated voltage.

2. The above parameters are measured with clear water. When the pressure drops, the amount will increase.

3. Allowable ambient temperature :0~40 degrees Celsius

4. Allowable liquid temperature :0~40 degrees Celsius

5. Allowable voltage range: within 10%± rated voltage

1） Special circumstances of the allowable voltage range, such as the transfer of slurry, please consult us.

2) due to product improvement, product specifications may change, without prior notice, can be adjusted.
