Introduction

The pump is made of special material, adopt unique strueure. It's widely used in factories, ore mining, railway,river to carry hot water from underground. Electrical machine and pump work as a whole.

Advantages

(1)Electrical machine and pump work as a whole,safe very much.

(2)No special requirments to pipe.

(3)Easy to be operated, convenient maintance, no need for pump room.

(4)Saving.

Working conditons

Requirements to power

(1)Rated frequency is 50Hz, rated voltage is 380±5%V three-phase AV power

(2)The transformer's load should not exceed 75% of its capacity.

(3)When the transformer is far away from mine, you should pay attention to line pressure drop. If the motr's power is bigger than 45kw, distance between the transformer and mine should not longer than 20m, the transmission line should be two levels more than distribution cable.

Material

Impeller:cast iron or tin bronze

Pump case:cast iron or stainless steel

Pump shaft:Cold pull chromium plating steel or stainless steel.
