A distribution valve for concrete transport pump

Practical Considerations in Pump Suction Arrangements

Check valves are installed on pump discharge lines to prevent liquid flow reversal with the succession of pumping. In a similar fashion, a foot valve is simply a form of check valve, usually in a vertical position, usually incorporating a strainer, installed in the pump suction line (see Figure 3). The purpose of the foot
