CHAPTER 2 MAIN STRUCTURE AND USE
1. Main Structure.
Water Pump and High Pressure Pump consists of Gasoline engine and pump kit. The pump is
fixed on a frame with shock absorbers.
The self-priming pump consists of pump body, pump cover, flow guidance, impeller and seals,
etc. Shaft sealing is machinery type sealing and the inlet of pump is higher than the inlet of impeller so
that is can self prime and you only need to fill water into the body of the pump. The inlet of pump is
fixed with a one-way valve to prevent liquid from being drained into water pool from the pump body
by siphon after stopping the machine. It must guarantee store enough liquid in the pump body for next
start.
The self-priming pump’s flow guidance and impeller are made from high strength cast iron, high
pressure pump’s flow guidance and impeller are made from high quality die casting of aluminum alloy.
To meet different use, high-pressure pump can equip with different accessories.
2. Main point of use
(1) The coupling of suction pipe to the pump must be tight, reliable without any leakage.
(2) A filter net must be added into the inlet of suction pipe as a protection to avoid impurity be
sucked into the pump and stick or damage the impeller.
(3) Prime the pump until the water overflow.
(4) Do not run it at high speed unless you prime it.
(5) Drain off the pump lor storage
3. Procedure of use
(1)Adding water
When start the pump for the first time, it only need to add a few water into the pump body. Please see
