Selection issue for high-pressure feed pump
Thread Content
Can diaphragm pumps achieve accurate flow control? If accurate flow is required at high head, is it necessary to use centrifugal pumps with a control valve at the outlet for fixed-value regulation? How can a diaphragm pump eliminate pulsations?
The flow rate can be adjusted, but precise control is not possible. The higher the head, the greater the pressure and the smaller the flow rate. To obtain an accurate flow rate, it is necessary to first measure the flow rate and then set the knob in place. Pulse elimination can be achieved using a pulsation buffer.
A twin-screw pump is a pump that produces absolutely no pulses or mixing; I’m not sure what you intend to transport
For pneumatic diaphragm pumps, there are many influencing factors: air pressure and air volume!
What is the flow rate and what is the pressure? Material composition? Temperature? Viscosity?
It depends on the specific pressure; if it’s not too high, an electric diaphragm pump can provide accurate regulation
