Warman Pumps: Assembly, Operating and Maintenance Instructions

INTRODUCTION

This publication, Part 2G, forms part of a set which together comprise the Assembly,Operating, and Maintenance Instruction Manual for the Warman Elastomer Lined Sump Pump, T ype ‘SPR’. Other publications in the set comprise the following: Part 1: Assembly, Operating and Maintenance Instructions – General Instructions for all Types of Warman Pumps. Part 3E: Ver tical Bearing Assembly, T ype ‘V’, Heavy Duty. Part 3F: Vertical Bearing Assembly, T ype ‘V’, Standard Duty.Part 1 has been written to more specifically describe the horizontal Type AH pump, and hence sections not relevant to vertical sump pumps should be disregarded. Part 2G applies to Type ‘SPR’ Warm an Elastomer Lined Sump Pumps.

These pumps are of heavy-duty construction, designed for submerged mounting in pits or sumps. They are particularly suited to continuous pumping of highly abrasive, and corrosive slurries in the Mining, Chemical, and General Process Industries. They feature an elastomer lined casing design, characterised by design simplicity, minimum number of parts, and light overall weight. Important design features of this range of Warman Slurry Pumps include:• Robust shafts• Optional Standard or Heavy duty bearing assemblies• Heavy duty screw thread Impeller attachment• Through-b olt design throughout• Replaceable casing components• No submerged bearings Type ‘SPR’ Sump Pumps may be supplied with either Standard Duty or Heavy Duty Bearing Assemblies. Standard Duty Bearing Assemblies are satisfactory for the bulk of sump pump applications. However for extreme operating conditions, involving high bearing loading, the longer bearing life yielded by the Heavy Duty Bearing Assemblies will often justify their use. Pumps fitted with Standard Duty Bearing Assemblies are characterized by a numeral representing PUMP SIZE (ie discharge pipe size in mms), immediately followed by FRAME TYPE (ie ‘V’), FRAME SIZE, and an optional IDENTIFIER for High Head models (ie ‘H’),followed by - PUMP TYPE (ie ‘- SPR’), eg 100VE-SPR, 65VDH-SPR Sump Pumps. High head Sump Pumps (eg 65VDH-SPR) are fitted with large diameter shafts for increased stiffness, which results in increase of the critical vibration speeds, and correspondi ng maximum pump speeds, to higher values than for the equivalent standard Bearing Assembly.
