Pumps

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
