F] CABLE GLAND ASSEMBLY: THE PUMP IS SUPPLIED WITH 50 FEET CABLE AS STANDARD.
THE CABLE IS A 4 CORE EPR SHEATHED AND INSULATED CONFORMING TO INT'L STD. 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. A WATER DAM ARRANGEMENT IS ALSO PROVIDED WHICH SEALS THE
INDIVIDUAL CORES OF THE CABLE. THIS FEATURE IS UNIQUE AND IS ESSENTIAL TO
PREVENT WATER SEEPING THROUGH THE CORES OF THE CABLE INTO THE TERMINAL CHAMBER
IN THE EVENT OF A CUT CABLE. THE CABLE IS ALSO SHEATHED FOR THE FIRST ONE METER
BY MEANS OF A CABLE GRIP MADE OF STAINLESS STEEL. 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.
G] ELECTRICAL INFORMATION: MOTORS ARE TYPICALLY DESIGNED TO OPERATE ON
230/460V AT 60 HZ. EXPORT DESTINED PUMPS ARE PREWIRED FOR SINGLE VOLTAGE AND
FREQUENCY. MAXIMUM DEVIATION IN VOLTAGE ALLOWED IS -/+ 6% AND FREQUENCY -/+ 3%.
