An alternate solution is to reduce the NPSH requirement of the pump by one of the following methods: 1. Evaluate system head conditions, NPSH available, and, if possible, reduce pump capacity. 2. Change pump impellers to obtain low NPSH design. 3. Replace the pump bowl assembly with a different model ,capable, of operating with the system NPSH available.

In an open system, one can raise the liquid level to increase suction ,pressure, or lower the pump. Sometimes one may need to increase the suction line size in order to lower the friction losses. A closed system may require installation of a booster pump, raising system ,pressure,, or maybe a different pump with a lower NPSH R requirement.

When a force-feed ,pump, encounters a downstream restriction, ,pump, discharge ,pressure, increases. If discharge ,pressure, exceeds ARV ,cracking pressure,, the ARV bypasses excess oil back to the low-,pressure, inlet side of the ,pump, (FIGURE 3-15 – High ,Pressure,).

Turn on power and wait for ,pump, to prime, which may take up to five (5) minutes. Priming time will depend on vertical length of suction lift and horizontal length of suction pipe. If ,pump, does NOT prime within five minutes, stop motor and determine cause. Be sure all suction and discharge valves are open when ,pump, is running.

An additional advantage can be found in the M9 ,pump, head with a reinforced suction stroke thanks to the spring-actuated diaphragm return movement. Thanks to this design, the Lewa M9 ,pump, heads have suction characteristics unlike those of other pumps. These ,pump, heads can operate without cavitation, even at low net positive suction head (NPSH) values.

Coordinate measuring machines (CMM), ,capable, of accuracies greater than 0.001 inch, and integrated solid modeling software are two of the most important tools used in reverse engineering. With these new standards in measurement and modeling, reverse engineering groups can duplicate components with even the tightest of tolerances—including those in nuclear applications.

This property is absolutely vital when pumping condensate, because the tanks are usually positioned at the same level as the pump and the fluids have a lower steam ,pressure,. Without the optimised suction characteristics of the M9 pump heads, the tank set-up or the tank itself must be modified to raise the net positive suction head (NPSH) value, which would be very costly.
