The design of the main pump piston pump bp 11 In the next naparpate lipiineacilld Ulit domestic modern piston llacocon, positively recommending “x yourself” and ships or have the perspective of using you Fig. 9. shows the design of the ENP – 7 pump with a drive from moth of koleichatoo shaft. Mark “asosa” means: electrically driven. II- “acoc. II – nopillileon. 7 – model number The pump ENP – 7 is designed for pumping seawater 11 petroleum products with a temperature of up to 100 C. and benzo” and with a temperature of up to 25 ° C. Specialized factories This pump is equipped with a DC / DC drive. AC electric motor with a diesel engine heat engine. Mark ENP.7 corresponds to a pump with an electric motor, – constantly ° current The pump consists of two main parts – hydraulic n at. water 11 “composite welded frame 113 sheets of steel.

a reducer (with spur gear helical gears) to the drive shaft of the pump. The drive crankshaft and gearbox receive lubrication from the oil distribution box, and which is pumped from the tank through a filter with a gear pump. mounted on the gear housing. If the pump is used to pump gasoline or other essential oil products, then hydraulic cylinders are supplied, special glands and armor must be attached to the pump tool.
