Product overview
Adjustable metering range: 0-400l / h, large pressure range: 0-1.0mpa drive mode: motor drive 220 V, 380V control mode: manual, automatic control (can receive 4-20mA signal to adjust the flow
Cast aluminum shell, high heat dissipation performance, light overall weight, suitable for all kinds of acid and alkali solution, non-toxic and tasteless.
It adopts cam mechanism. It has no leakage on the whole and can be placed on the medicine tank or pipeline.
Contact medium pump head is made of PVC, PTFE and stainless steel.
It is widely used in water treatment industry with low pressure requirements due to its high cost performance.
When the pump is running or stopped, the flow can also be adjusted at will, and the output can be quantified.
The diaphragm is pressed by multi-layer composite structure. The first layer is super tough Teflon acid resistant film, the second layer is EPDM elastic rubber, the third layer is 3mm thick SUS304 supporting iron core, the fourth layer is reinforced by reinforced nylon fiber, and the fifth layer is completely wrapped with EPDM elastic rubber, which can effectively improve the service life of the diaphragm.
