60 SERIES OM−06224 INTRODUCTION This Installation, Operation, and Maintenance manual is designed to help you achieve the best performance and longest life from your GormanRupp pump. This pump is a 60 Series, centrifugal model with an enclosed impeller. The pump is designed for high pressure distribution of clear water in irrigation or fire fighting service. It is closed coupled to a single cylinder, Yanmar L100V diesel engine and mounted on a common hand−carry base.
0 SERIES OM−06224 SAFETY - SECTION A This information applies to 60 Series engine driven pumps. Refer to the manual accompanying the engine before attempting to begin operation. This manual will alert personnel to known procedures which require special attention, to those which could damage equipment, and to those which could be dangerous to personnel.
OM−06224 Do not remove plates, covers, gauges, pipe plugs, or fittings from an overheated pump. Vapor pressure within the pump can cause parts being disengaged to be ejected with great force. Allow the pump to cool before servicing. Do not operate an internal combustion engine in an explosive atmosphere. When operating internal combustion engines in an enclosed area, make certain that exhaust fumes are piped to the outside.
60 SERIES OM−06224 INSTALLATION − SECTION B Review all SAFETY information in Section A. Since pump installations are seldom identical, this section offers only general recommendations and practices required to inspect, position, and arrange the pump and piping. specific application.
OM−06224 60 SERIES PREINSTALLATION INSPECTION POSITIONING PUMP The pump assembly was inspected and tested before shipment from the factory. Before installation, inspect the pump for damage which may have occurred during shipment. Check as follows: Lifting a. Inspect the pump and engine for cracks, dents, damaged threads, and other obvious damage. b. Check for and tighten loose attaching hardware. Since gaskets tend to shrink after drying, check for loose hardware at mating surfaces.
60 SERIES Line Configuration Keep suction and discharge lines as straight as possible to minimize friction losses. Make minimum use of elbows and fittings, which substantially increase friction loss. If elbows are necessary, use the long-radius type to minimize friction loss. Connections to Pump Before tightening a connecting flange, align it exactly with the pump port. Never pull a pipe line into place by tightening the flange bolts and/or couplings.
OM−06224 of one or both pumps. To avoid this, position the suction inlets so that they are separated by a distance equal to at least 3 times the diameter of the suction pipe. Suction Line Positioning The depth of submergence of the suction line is critical to efficient pump operation. Figure 3 shows 60 SERIES recommended minimum submergence vs. velocity. NOTE The pipe submergence required may be reduced by installing a standard pipe increaser fitting at the end of the suction line.
OM−06224 60 SERIES OPERATION − SECTION C Review all SAFETY information in Section A. Follow the instructions on all tags, labels and decals attached to the pump. This pump is designed to handle clear water for high pressure distribution. Do not attempt to pump volatile, corrosive, or flammable liquids which may damage the pump or endanger personnel as a result of pump failure. Never tamper with the governor to gain more power. The governor establishes safe operating limits that should not be exceeded.
OM−06224 Do not remove plates, covers, gauges, pipe plugs, or fittings from an overheated pump. Vapor pressure within the pump can cause parts being disengaged to be ejected with great force. Allow the pump to cool before servicing. Strainer Check If a suction strainer has been shipped with the pump or installed by the user, check the strainer regularly, and clean it as necessary. The strainer should also be checked if pump flow rate begins to drop.
60 SERIES OM−06224 TROUBLESHOOTING − SECTION D Review all SAFETY information in Section A. Before attempting to open or service the pump: 1. Familiarize yourself with this manual. 2. Shut down the engine and disconnect the spark plug wire to ensure that the pump will remain inoperative. 3. Allow the pump to completely cool if overheated. 4. Check the temperature before opening any covers, plates, or plugs. 5. Close the suction and discharge valves. 6. Vent the pump slowly and cautiously. 7.
OM−06224 TROUBLE PUMP STOPS OR FAILS TO DELIVER RATED FLOW OR PRESSURE (cont.) PUMP REQUIRES TOO MUCH POWER EXCESSIVE NOISE PAGE D − 2 60 SERIES POSSIBLE CAUSE PROBABLE REMEDY Impeller or other wearing parts worn or damaged. Replace worn or damaged parts. Check that impeller is properly centered and rotates freely. Impeller clogged. Free impeller of debris. Suction lift too high. Measure lift w/vacuum gauge. Reduce lift and/or friction losses in suction line. Pump speed too slow.
60 SERIES OM−06224 PREVENTIVE MAINTENANCE Since pump applications are seldom identical, and pump wear is directly affected by such things as the abrasive qualities, pressure and temperature of the liquid being pumped, this section is intended only to provide general recommendations and practices for preventive maintenance. Regardless of the application however, following a routine preventive maintenance schedule will help assure trouble-free performance and long life from your Gorman-Rupp pump.
OM−06224 60 SERIES PUMP MAINTENANCE AND REPAIR − SECTION E MAINTENANCE AND REPAIR OF THE WEARING PARTS OF THE PUMP WILL MAINTAIN PEAK OPERATING PERFORMANCE. STANDARD PERFORMANCE FOR PUMP MODELS 62 1/2A1− Based on 70_ F (21 _ C) clear water at sea level with minimum suction lift. Since pump installations are seldom identical, your performance may be different due to such factors as viscosity, specific gravity, elevation, temperature, and impeller trim.

OM−06224 PUMP AND SEAL DISASSEMBLY AND REASSEMBLY Review all SAFETY information in Section A. Follow the instructions on all tags, label and decals attached to the pump. This pump requires little service due to its rugged, minimum-maintenance design. However, if it becomes necessary to inspect or replace the wearing parts, follow these instructions which are keyed to the sectional views (see Figures 1 and 2) and the accompanying parts lists.
60 SERIES OM−06224 Seal Removal and Disassembly (Figure 2) Remove the impeller adjusting shims (4). Tie and tag the shims or measure and record their thickness for ease of reassembly. Remove the seal spring and slide the shaft sleeve (5) and rotating portion of the seal off the engine shaft as a unit. Apply oil to the sleeve and work it up under the bellows. Slide the rotating portion of the seal off the sleeve.

60 SERIES OM−06224 For maximum pump efficiency, the impeller should be centered within the volute scroll. Use the casing gaskets (10) and the impeller shims (4) to center the impeller as described below. pump casing and impeller as shown in Figure 4. Use these measurements to calculate the required impeller location (dimension E). Add or remove impeller adjusting shims until dimension E is obtained.
