GENERAL PUMP 1. INTRODUCTION A member of the Interpump Group SM SERIES This manual describes the use and maintenance instructions of the SM pump, and should be carefully read and understood before using the pump. Correct use and adequate maintenance will guarantee the pumps trouble-free operation for a long time. General Pump declines any responsibility for damage caused by misuse or the non-observance of the instructions indicated in this manual.
GENERAL PUMP A member of the Interpump Group 3. SAFETY SM SERIES 3.1 General Safety Indications Improper use of pumps and high pressure systems, and/or failure to observe the installation and maintenance instructions may cause serious injury to people and/or damage to property.
GENERAL PUMP A member of the Interpump Group SM SERIES Note: appropriate clothing will effectively protect against water spray, but it may not offer adequate protection against the direct impact of water jets or sprays from a close distance. Some circumstances may require further protection. 3. It is generally best to organize personnel into teams of at least two people capable of giving mutual and immediate assistance in case of necessity and of taking turns during long and demanding operation. 4.

GENERAL PUMP A member of the Interpump Group 6. DIMENSIONS AND WEIGHT SM SERIES For dimensions and weight, please refer to fig. 2. 7. INFORMATION ABOUT PUMP USE Weight: 573 Lbs./260 Kg. fig. 2 The SM pump was designed to operate with filtered water (see paragraph 9.7) and at maximum temperature of 104o F (40o C). Other fluids may be used only upon the approval of The Customer Service Department . 7.1 WaterTemperature The max water temperature is 85o F (30o C). 7.
GENERAL PUMP A member of the Interpump Group 7.4 Recommended Lubricant Oil Types & Manufacturers SM SERIES The pump is delivered with lubricant oil compliant with room temperatures ranging between 32o and 89.6o F (0o and 30oC ). Some recommended lubricant types are indicated in the table below; these lubricants are treated with additives in order to increase corrosion protection and resistance to fatigue. As an alternative, Automotive SAE 85W-90 gearing lubricants may also be used.
GENERAL PUMP A member of the Interpump Group SM SERIES In any case, oil must be changed at least once a year since it may deteriorate by oxidation. For room temperatures that differ from that mentioned earlier, follow the indications contained in the diagram below, keeping in mind that the oil must have a minimum viscosity of 180 cSt. VISCOSITY/ROOM TEMPERATURE DIAGRAM Exhausted oil must be collected in an appropriate container and disposed of in appropriate locations.
GENERAL PUMP A member of the Interpump Group 8. PORTS AND CONNECTIONS SM SERIES SM Series pumps are equipped with (see fig. 4): 1. 2 inlet ports “IN”, 1-1/2” Gas The line can be connected to either of the two inlet ports; the ones not being used must be hermetically sealed. 2. 2 outlet ports “OUT”, Ø 13mm 3. 2 service ports, 1/2” Gas. These can be used for the pressure gauge 4. 1 drain port “DRAIN” supplied with a 90o adjustable quick coupling for polyamide hose with Ø 12mm.
GENERAL PUMP 9. PUMP INSTALLATION A member of the Interpump Group SM SERIES 9.1 Installation The pump must be installed in a horizontal position using the M 16x1.5 threaded support feet. Tightenthe screws with a torque of 148 ft. lbs. (200 Nm). The base must be perfectly flat and rigid enough as not to allow bending or misalignment on the pump coupling and axis/transmission due to torque transmitted during operation.
GENERAL PUMP A member of the Interpump Group SM SERIES 9.2 Direction of rotation The PTO rotation is indicated by an arrow located on the reduction gear cover. From a position facing the pump head, the rotation direction will be as in fig. 6. 9.3 Version change and reduction gear positioning The pump version is defined as right when: observing the pump facing the head side, the crankshaft is on the right side.
GENERAL PUMP A member of the Interpump Group SM SERIES The reducer’s position may be changed only by specialized and authorized personnel by carefully following the instructions in the repair manual. 9.4 Hydraulic Connections To isolate the plant from the vibrations produced by the pump, we recommend building the first section of hose adjacent to the pump (for both intake and outlet) with flixible hose.
GENERAL PUMP A member of the Interpump Group SM SERIES 9.7 Filtration The level of filtration permitted for this series of pumps must be maximum 20 µm (micron). Normally this is obtained by a battery of at least three filters, positioned as shown in fig. 8. The filters must be installed as close as possible to the pump.
GENERAL PUMP A member of the Interpump Group SM SERIES 9.9 Internal Diameter of the Hose Line To determine the internal diameter of the hose, please refer to the following diagram. Inlet Hose With a flow rate of ~21 GPM (80 l/mn) and water speed of 0.5 m/sec. The diagram line that connects the two scales intersects the central scale, indicating the diameters, at a value of ~ 2.3 inch (58 mm). Outlet Hose With a flow rate of ~21 GPM (80 l/mn) and water speed of 5.5 m/sec.
GENERAL PUMP A member of the Interpump Group SM SERIES 9.10 V-belt Transmission As indicated in point 9.1, the pump can be controlled by a v-belt system only in exceptional cases. For proper layout sizing, consult our Customer Service Department 9.11 Transmission of power from the second crankshaft SM series pumps can, upon request, be supplied with an auxiliary power outlet on the opposite side of the activation.
GENERAL PUMP A member of the Interpump Group 10. START-UP AND OPERATION SM SERIES 10.1 Preliminary Inspections Before Start-up Be sure that: The inlet line is connected and up to pressure (see Chapter 9) the pump must NEVER run dry. 1. The inlet line must be perfectly airtight. 2. All the On-Off valves between the pump and the feeding source are completely open. The outlet line must discharge freely in order to allow the air in the pump to be expulsed easily, thus facilitating pump priming. 3.
GENERAL PUMP SM SERIES A member of the Interpump Group 10.3 Seal Pack Cooling Circuit During operation, some water from the cooling circuit seal packings will be discharged from port 1 (fig. 10). The drainage from this circuit must be redirected to the inlet line upstream of the booster pump (fig. 10) or to the collection tank. 11. PREVENTIVE MAINTENANCE To guarantee pump reliability and efficiency, comply with the maintenance intervals as indicated in the table below.
GENERAL PUMP A member of the Interpump Group 12. PUMP STORAGE SM SERIES 12.1 Inactivity for Lengthly Periods If the pump is started for the first time after a long period of inactivity, before putting it into operation check the oil level, inspect the valves as indicated in Chapter 10, and then follow the prescribed startup procedures. 12.2 Filling the Pump With An Anti-Corrosion Emulsion or Anit-freeze By Using An External Diaphragm Pump As In The Layout Shown in Paragraph 9.6.
