Roots Oil Pump LC is low in rpm, small in volume, strong in self-adorptivity, easy in use/repair and wide in medium-application range, it can also work on drive and reversely. Roots Pump LCw is, based on the Roots Pump LC, to transfer asphalt and solve condensate-oil problem, so it is of double thermal-insulation/preheating layers on the casing or cover and use the steam or heat-conducting oil in circulation for thermal insulation/preheating of the pump working chamber; so it is an ideal transfer set in trades of petroleum, chemicals, asphalt, foodstuffs, municipal works and communications etc. Roots Pump LCw is, based on the Roots Pump LC and to meet the needs at ex-proof market, specially designed in the parts touching the flowing medium, good for the volatile-inflammables of gasoline, diesel oil etc. being ideal for the trades of petroleum, chemicals, asphalt, foodstuffs, municipal works and communications etc. This series is in conformity with Standard API 676.
Performance range: Q= 5～100 m3/h; pressure 0.3～0.6 MPa; applicable range of medium viscosity 5～5000 mm2/s; medium temperature ≤200℃.
