A pump curve provides details of pump efficiency, net positive suction head (NPSH), various impeller diameters, and pump power consumption.

Application guidelines for centrifugal pumps are location of flat when using eccentric reducers, all pump suction lines must be designed to accommodate, the suction of any centrifugal pump must continuously flooded and suction pumping shall contain no vertical loops or air pockets.

A pump head is a measure of fluid energy.

Regulating valves are used extensively to regulate the flow of fluid. Different types of regulating valves are globe, needle, butterfly, ball, plug and diaphragm valves.

Backflow prevention is used to prevent backflow. In backflow prevention the valves are self actuating and the valve disc is kept open by the forward flow of fluid.

Protection valves are used to protect piping and equipment from being subjected to pressures. Protection valves include a rupture disc designed to burst open at a predetermined pressure.

Stop or isolation valves include gate, globe, ball, butterfly, play and diaphragm valves.

Reduction in length, directional changes, and diameter variations decrease cost.

Higher viscosity fluid = powerful pumpings of fluid and supporting of pipe.

Head loss is calculated using a number of calculations depending on type of piping and attached equipment.

Selection of pipe thickness would be dependent on same parameters utilized in piping size selection criteria.
