Page 12: Pump Description
2.0 Pump description TopGear H-pumps are rotary positive displacement pumps with internal gear. They are made of stainless steel, nodular iron or cast steel. TGH-pumps are assembled from modular elements, which allows a variety of constructions: different shaft sealings (packing and/or mechanical seal), heating/ cooling jackets (steam or thermal oil), several sleeve bearings, gear and shaft materials and mounted relief valve. - Page 13 8.

3.0 General technical information Pump standard parts Top cover Intermediate casing Pump shaft Bearing bracket Idler pin Rotor Pump cover Idler gear Pump casing Operating principle As the rotor and idler gear unmesh, an underpressure is created and the liquid enters the new created cavities. Liquid is transported in sealed pockets to the discharge side. -
Page 16: Self-Priming Operation
3.2.1 Self-priming operation TopGear pumps are self-priming when sufficient liquid is present in the pump to fill up the clearances and the dead spaces between the teeth. (For self-priming operation see also section 3.18.6.2 Piping). 3.2.2 Safety relief valve – Working principle The positive displacement principle requires the installation of a safety relief valve protecting the pump against overpressure. -

Page 18: Pressure
Pressure For performance on pressure, three kinds of pressures must be considered: Differential pressure or working pressure (p) is the pressure on which the pump normally operates. The maximum differential pressure for all TopGear H-range pumps is 16 bar. Maximum allowable working pressure (p.m) is the pressure on which the pump casing is designed and that can been achieved occasionally when the operating pressure rises over the normal operating pressure e.g. -

The pump shaft is sealed by means of packing rings and the bronze shaft bearing is placed outside the pumped medium and is designed to work as a packing gland. Because of the fact that, under normal conditions, the shaft bearing does not come into contact with the pumped medium, bronze can be used as material. -

Page 39: Suction And Discharge Pipes
3.18.6 Suction and discharge pipes 3.18.6.1 Forces and moments Note! Excessive forces and moments on the nozzle flanges derived from piping can cause mechanical damage to pump or pump unit. Pipes should therefore be connected in line, limiting the forces on the pump connections. Support the pipes and make sure they remain stress-free during operation of the pump. -
Page 40: Isolating Valves
Self-priming operation At the start sufficient liquid must be available in the pump filling up the internal clearance volume and the dead spaces, allowing the pump to build up a pressure difference. Therefore, for pumping low viscosity fluids, a foot valve with the same or larger diameter than the suction pipe must be installed or the pump can be installed without foot-valve but in U-line. -
Page 41: Heating Jackets
3.18.7.2 Heating jackets 1. S-type jackets The S-jackets are designed for use with saturated steam (max 10 bar, 180°C) or with non-dangerous media. They are provided with threaded connections Bl (see chapter 6.0 for the dimensions). The connection can be done by threaded pipes or pipe connections with sealing in the thread (conical thread applying ISO 7/1) or sealed outside the thread by means of flat gaskets (cylindrical thread applying ISO 228/1). -

Page 48: Electric Motor Drive
3.18.9.4 Electric motor drive • Before connecting an electric motor to the mains check the current local regulations of your electricity provider as well as the EN 60204-1 standard. • Leave the connecting of electric motors to qualified personnel. Take the necessary measures to prevent damage to electrical connections and wiring. -
Page 49: Shaft Coupling
3.18.9.6 Shaft coupling Internal gear pumps demand a relatively high starting torque. During the operation shock loads are occurring due to pulsations inherent to the gear pump principle. Therefore, choose a coupling which is 1.5 times the torque recommended for normal constant load. Alignment The pump and motor shafts of complete units are accurately pre-aligned in the factory. -
Page 50: Instructions For Start-Up
3.19 Instructions for start-up 3.19.1 General The pump can be put into service when all arrangements described in chapter 3.18 Installation have been made. • Prior to commissioning, responsible operators have to be fully informed on proper operation of the pump/pump unit and the safety instructions. This instruction manual must at all times be available to the personnel. -
Page 51: Checklist - Initial Start-Up
3.19.4 Checklist – Initial start-up After thorough servicing or when the pump is to be put into service for the first time (initial start-up) the following checklist must be observed: Supply and discharge line c Suction and discharge pipes are cleaned. c Suction and discharge pipes are checked for leaks. -
