Two pumps in parallel if operator throttled back on discharge valve of second
A reduction in total flow rate to condenser
Gate
Should not be used to regulate flow
Air entering through the pump seals
Will not cause a pump to cavitate
When throttling down he discharge vaulve of a brine pump
Bribe flow goes down and HP goes down
Parallel pump system
All pumps discharge into a common Header
Adjustable pitch motor sleeve
Permit adjustments to the pump speed
When bringing an additional condenser water pump on live
Suction fully open, throttle discharge
Clogged strainer of a condenser water pump
High head pressure
Two condenser water pumps with total pressure drop of 40psi
One pump with total pressure drop of 40 psi
What would cause he condenser water temp to rise when pump is running
Malfunctioning tower fan
Units to rate flow
Gallons per minute GPM
Copper tubes extended from pump volume to fittings adjacent to pump shaft
Cool the mechanical seals
Centrifugal water pump has packing glands if
There are bolts on the plate around the shaft to tighten the packing
Confirms that water is moving through the piping system
Flow switch
Valve that creates he least amount of pressure drop
Gate valve
If the check valve located on the discharge side of a pump does not function properly which of the following may take place when the pump is started
Risk of possible damage to the pump motor
Petcock
Vent the casing
