Water Pump Accessories

A: Manual diaphragm pumps are widely used in the chemical industry due to their ability to handle a wide variety of corrosive and abrasive fluids. In this industry, it is essential to choose the right pump for each application to ensure optimum performance and long life due to the nature of the fluids pumped.

A: By preventing reverse flow, check valves prevent the mixing of different media between two reservoirs. For example, in a water treatment plant, check valves prevent treated water from flowing back into the untreated water reservoir.

A: Therefore, it is necessary to install a check valve at the outlet of the pump or pressure source. In piping systems, it is sometimes necessary to install check valves at high locations. This usually occurs in vertical pipes or in high sections of pipes.

A: As a general rule of thumb, valves of any sort should be located in a straight run of ten to fifteen pipe diameters in total length. There should be five diameters of straight pipe upstream, and five to ten diameters downstream of where a valve is to be installed.

A: The check valve will help your water system maintain pressure when the pump shuts off and also prevent backspin, upthrust, and water hammer. It is recommended that at least one check be installed in all submersible well pump installations. Many well pumps have built-in check valves.

A: Another instruction from the bronze pressure reducing valve manufacturers is that the check valve must be installed at the outlet of the pump and in front of the outlet control valve for maintenance.

A: The primary advantage of a check valve is they prevent reverse flow while typically requiring no external actuation. They also provide a fast-acting solution to preventing backflow.

A: Material Selection: Material used for valve construction must stand up to piping system and media demands associated with the specific type of gas or liquid flowing through the piping system.
Performance Requirements: Performance considerations include the capability of the valve to handle various temperature and pressure instances.
Type and Size: Selection of the right check valve includes control considerations, typically related to increased safety in hazardous applications as well as sizing the valve to properly accommodate the piping system's flow conditions.
Maintenance: In addition to considering the frequency of maintenance or replacement, operators must also think about the valve's resistance to clogging, jamming, or otherwise malfunctioning.
