Type SP is all metal material, suit for abrasive duty.
Type SPR is elastomer protected, suit for acid / abrasive duty.
Type SP and SPR pumps are vertical, centrifugal slurry pumps submerged in sump to work. They are designed for delivering abrasive, large particle and high density slurries. These pumps have no need of any shaft seal and sealing water. They can also be operated normally for insufficient suction duties.
which is suited for the working condition of deeper level. The guide bearing construction is added to the pump on the basis of the standard pump, so the pump is with both more steady operation and wider application range, but flushing water should be attached to the guide bearing.
Wet parts of type SP pump are made of abrasion-resistant metal
All parts of type SPR pump immersed in liquid are lined with rubber outer liner. They are suited to transport no-edge angle abrasive slurry
The type with [L" is a sump pump of extension shaft series, which is suited for the working condition of deeper level. The guide bearing construction is added to the pump on the basis of standard pump, so the pump is with both more stable operation and wider application range. But flushing water should be douche the guide bearing.
