THE HYDRAULIC ELEMENTS
.
THE STAINLESS STEEL IMPELLER RUNNING AGAINST A CAST IRON SUCTION COVER AND WEAR
PLATE, CONSTITUTE THE HYDRAULIC ELEMENTS OF THE PUMP. THE IMPELLER CAN BE
ADJUSTED TO MAINTAIN MAXIMUM OUTPUT AFTER USAGE WITHOUT PARTS REPLACEMENT. IT
IS IMPORTANT, HOWEVER, TO MAINTAIN CLEARANCES BETWEEN THE WEAR PARTS.
CABLE GLAND ASSEMBLY. (REFER DRG.)
THE PUMP IS SUPPLIED WITH 20 FEET CABLE AS STANDARD. THE CABLE IS A 3 CORE EPR
SHEATHED AND INSULATED CABLE CONFORMING TO INTERNATIONAL STANDARDS. THE CABLE
IS WATERPROOF AND CAN BE COMPLETELY SUBMERGED IN WATER. THE CABLE IS TERMINATED
IN THE PUMP AT THE CABLE GLAND. THE GLAND ASSEMBLY SEALS THE CABLE ON THE
OUTSIDE SHEATH. THE CABLE IS ALSO ANCHORED TO THE BODY OF THE PUMP USING A
SHACKLE - THIS IS ESSENTIAL TO ENSURE THAT THERE IS NO UNDUE STRAIN ON THE
CABLE IF THE PUMP IS PULLED OR LOWERED INADVERTENTLY BY MEANS OF THE CABLE.
COMPLETE DETAILS OF THE CABLE GLAND ASSEMBLY ARE SHOWN IN THE DRAWING.

1. ALL "O" RINGS TO BE REPLACED WHENEVER PARTS ARE DISMANTLED.
2. SEAL ELASTOMER PARTS SHOULD NEVER BE RE-USED AFTER DIS-ASSEMBLY.
3. DO NOT REFILL BEARING GREASE. ALWAYS REPLACE COMPLETE NEW BEARING WITH
