GENERAL PUMP 1. INTRODUCTION A member of the Interpump Group This manual describes the use and maintenance instructions of the VF 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 3.3 Safety of Operation (continued) 2. That pump intake filters are perfectly clean; we advise to use a device that indicates the filters clogging level. 3. That electrical parts are adequately protected and in perfect condition. 4. That high pressure hoses do not show apparent signs of abrasion, and that fittings are in perfect shape.

GENERAL PUMP VF SERIES A member of the Interpump Group 7.INFORMATION ABOUT PUMP USE The VF pump has been designed to operate with filtered water (see paragraph 9.7) and at room temperature. Other fluids may be used only upon the approval of The Customer Service Department . Check the oil level by using the appropriate oil level dipstick with minimum and maximum value notches (1), fig. 3. Refill if needed.
GENERAL PUMP VF SERIES A member of the Interpump Group 8. PORTS AND CONNECTIONS VF Series pumps (see fig. 4) are provided with: 1. 2 inlet ports “IN”, 3/4” 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 8 mm 3. 2 auxiliary ports, 1/2” gas; they can be used for the pressure gauge and the safety valve. 4.
GENERAL PUMP A member of the Interpump Group 9.2 Direction of Rotation An arrow situated on the crankcase near the shaft indicates the correct direction of rotation. Standing in front of the pump head, the direction of rotation must be as shown in fig. 6. VF SERIES 9.4 Hydraulic Connections In order to isolate the system from the vibrations produced by the pump, we advise to build the first section of the duct near the pump (both for intake and delivery) with flexible hose.
GENERAL PUMP A member of the Interpump Group 9.6 Suction Line (continued) 11. The pressure gauge for checking booster pressure must be installed near the plunger pump’s outlet port, and always after the filters. 9.7 Filtering The filtration degree for these pumps must be max. 20 micron; this is normally obtained by means of a series of at least three filters, positioned as indicated in fig. 7.
GENERAL PUMP A member of the Interpump Group The diagram does not take into consideration the hose and valve resistance, the pressure drop due to the hose length, the viscosity and the temperature of the pumped fluid. If necessary, contact our Customer Service Department. 9.10 V-belt Transmission The pump may be driven by a v-belt system. For this pump model, we suggest to use 4 XPB belts (16.
GENERAL PUMP A member of the Interpump Group 9.11 Transmission Definition (continued) c) Set belt tension according to the Manufacturer’s recommendations; an excessive value will abnormally stress the bearing, reduce its duration, and cause premature wear of the pulley. The tension value depends on different variables as indicated in paragraph 9.12. d) Belt length has a natural tolerance ≥ ± 0.75%; for this reason the three belts must be purchased in pairs.
GENERAL PUMP A member of the Interpump Group In case the pump has not run for a long period of time, verify the correct operation of the suction and delivery valves. 10.2 Start-up 1. When starting the pump for the first time, check for the correct direction of rotation. 2. The pump must be started off-load. 3. Verify correct feeding pressure. 4. During operation check that the rotating speed does not exceed the rated value. 5. Before putting the pump under pressure let it run for at least 3 minutes. 6.
GENERAL PUMP A member of the Interpump Group 13. PRECAUTIONS AGAINST FREEZING In areas and periods of the year where there is risk of freezing, follow the instructions indicated in Chapter 12 (see paragraph 12.2). In the presence of ice, in no case must the pump be started until the entire circuit has been completely thawed out; not complying with this indication may cause serious damage to the pump. 14. WARRANTY TERMS The duration and the terms of the warranty are contained in the purchase contract.
