Cast Iron 3QGB Heating Bitumen Triple Screw Asphalt Pump Fuel Pump

With special spiral profiles of rotors, the medium transmission through rotors and housing's engaged changing chambers is achieved. It can deliver different liquids with lubrication, without particles or corrosion features, is widely applied in machinery, chemical, metallurgy, power generation, shipbuilding and building material fields for hydraulic, lubrication, fuel conveying functions. And it is a preferred substitute for centrifugal pumps, gear pumps and reciprocating pumps in some applications.

1. Customized design for inlet/outlet ports, with better accordance to liquid fluidity;
2. Component-based design for pressure relieve valve, with better protection for products;
3. Low noise, no impulse, no abrasion on screw, and long service life;
4. Simple and compact structure, low volume, light weight, high efficiency and good energy saving effect;

Medium viscosity: 3.0~1500 mm2/s;
Flow range: 35~1700 L/min;
Maximum pressure: 2.5 Mpa;
Max. temperature: 300 deg C

1. Pump fuel oil, crude oil, heavy oil, asphalt, rubber, resin such various types of lubrication oil-type liquid in industries of petroleum
2. Chemical fiber, metallurgy, road construction, electricity, mining, shipbuilding, glass etc.
3. The double jacket casting allows the heat preservation liquid passing to keep or cool the thermal of media pumped.
