Mar 28, 2016 · Capacity Use HS-900 for capacity at a given Δ P. The application capacity should be between 50 percent and 100 percent of the selected valves’ capacity in HS-900. The capacity of the system will equal the lower of the two valves’ capacities, if they differ. Do not oversize the valves. Oversized valves will “hunt” and also wear prematurely. Higher "vacuum" levels requires use of separate lifting pumps and dedicated feeding reservoirs to the fuel pumps. The total "vacuum" in a fuel oil suction line can roughly be estimated to. 1 inch of vacuum for each foot of lift; 1 inch of vacuum for each 90 o elbow; 1 inch for each 10 feet of 3/8 inch horizontal suction pipe

Oct 18, 2018 · Be sure the supply line shut-off valve (if equipped) is fully open with no restrictions. This should be a “full-flow” ball valve with the same inside diameter (i.d.) as the supply hose. If feasible, locate a vacuum gauge that can be T’d into the supply line and plumb it at the pump inlet port.
Pipe sizing and layout of the suction line and the vent line are critical to the function of the Vent Line. Failure to get these design elements correct can result in an insufficient column of water in the vent line, such that when the pump draws from the vent line during normal operation, the pump will lose its prime and cavitate. The engineer ...
Nov 04, 2020 · Buying the right size unit isn’t rocket science, but it can be a little tricky. You must take into consideration the square footage of your house, the length of pipe required to service the system, and the suction necessary.
