Pump Body & Pump Casing in China
Pump body is also
known as pump casing, pump shell. Water pump body is usually made by gray
iron (grey iron) HT200 (ASTM NO.30, GG20, ISO200,
FC200, GC200). We called it HT200 in Chinese
standard.
Our foundry has
made many types of pump bodies for water pumps
manufacturers in Korea and USA. For the suitable
casting process, we suggest to use the green sand
for the outside surface, and use precoated resin
sand for the inside surface. This
process can keep the good inside surface and
quality, and will keep the costs as low as possible.
Usually, the water
pressure testing will be necessary for the pump
casing, but the pressure testing only is a
inspection method, the basic way to reach their
requirements is to improve the casting quality. Good
foundry, suitable casting process, strict quality
control are the good guarantee.
