3. Pump Performance Tests
3.1 Hydrostatic Test – Recent evidence of gydrostatic testing of pump for 10 minutes at a minimum pressure of 3,400 Kpa (500 p.s.i.).
APPLICABLE TO NEW OR REBUILT PUMPS ONLY.
Priming and Suction Capability Tests
Vacuum Test: The pump priming device, with a capped suction at least six metres (20 ft) long, shall develo9p 75 Kpa (22 inches of mercury) at altitudes up to 300 metres (1,000 ft) and hold the vacuum with a drop of not in excess of 34 Kpa (10 inches of mercury) in ten minutes.
For every 300 metres (1,000 ft) of elevation, the required vacuum shall be reduced 3.4 Kpa (1 inch of mercury).
The primer shall not be used after the 10 minute test period has been started. Tests shall be made with discharge outlets uncapped.
Suction Capability Test: The pump (in parallel or series) when dry, shall be capable of taking suction and discharging water with a lift of not more than 3 metres (10 ft) through six metres (20 ft) of suction hose of appropriate size, in not more that 30 seconds, and not over 45 seconds for 6,000 L/min (1320 Igpm) or larger capacity pumps. Where front or fear suction is provided on midship pumps, an additional 10 seconds priming time will be allowed. The test will be conducted with all discharge caps removed.
Capacity Test: Consists of drafting water (preferably with a 3 metre (10 ft lift)) and pumping the rated capacity at 1,000 Kpa (150 psi) net pump pressure for a continuous period of at least one hour.
Pressure Test: Under the same conditions as in 3.3.1 above, pumping 50% of the rated capacity at 1700 Kpa (250 psi) net pump pressure for at least ½ hour.
