Use of Check Valves in Submersible Well Pump Installations

Jan 16, 2019· Many well pumps have built-in check valves. Even if a pump does have a built-in check valve, we recommend that a check valve be installed in the discharge line within 25 feet of the pump and below the draw down level of the water supply. Although installers have different opinions, in deep wells we recommend that check valves be installed every ...

Typical P&ID arrangement for pumps - EnggCyclopedia

A check valve should be normally provided on the pump discharge to avoid reverse flow when the pump is not in operation. Downstream to the check valve on the pump discharge, minimum flow recirculation line for the pump needs to be provided. A flowmeter should be provided before the minimum flow line, as shown on the presented sample drawing.

Fitting distance from Pump - Pump engineering - Eng-Tips

Nov 04, 2004· The closer you have valves and other items are near the discharge of the pump the better these waves will be reflected and disturb the flow pattern of the liquid through the pump. You need distance between the pump and the first accessories such as valves etc so you get some mass of liquid that can somewhat attenuate this pressure wave.
