OVERLOAD PROTECTION
.
IT IS ESSENTIAL THAT A STARTER BE USED WHEN OPERATING THE PUMP. CHOOSE THE
CORRECT RATING OF STARTER AS PER THE NAME PLATE OF THE PUMP. THE OVERLOAD
SETTING ON THE STARTER RELAY SHOULD BE SET TO THE FULL LOAD CURRENT OF THE PUMP
AS INDICATED ON THE NAME PLATE. FOR SINGLE PHASE PUMPS A PANEL BOARD IS
NECESSARY.
SPECIAL CONTROL BOXES SUITABLE FOR THE PUMP ARE AVAILABLE WITH US INCORPORATING
ALL PROTECTIONS NECESSARY.
LUBRICATION
.
NO ROUTINE MAINTENANCE OR LUBRICATION IS NECESSARY. THE BEARINGS ARE GREASE
LUBRICATED AND SEALED FOR LIFE. THE MECHANICAL SEAL AND OIL SEAL RUN IN AN OIL
BATH. NO TOPPING UP IS NECESSARY BUT THE CONDITION OF THE OIL SHOULD BE CHECKED
ONCE IN SIX MONTHS. THIS IS BY FAR THE EASIEST WAY TO ASCERTAIN THE INTEGRITY
OF THE SEAL FACES. (REFER OVERHAUL INSTRUCTIONS)
