3.0 General technical information Pump standard parts Lantern piece Intermediate Pump shaft casing Top cover Idler pin Rotor Pump casing Pump cover Idler gear 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.
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 3.17.6.2 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.
Main characteristics The pump size is designated by the displacement volume of 100 revolutions expressed in litres (or dm ) but rounded followed by the nominal port diameter expressed in millimetres. ∆p Vs-100 n.max n.mot Q.th Q.th p.test TG BLOC pump size (mm) (mm) (mm)
Pressure Differential pressure or working pressure (p) is the pressure on which the pump normally operates. TopGear BLOC-line has the maximum differential pressure at 16 bar. (86-100 10 bar) The hydrostatic test pressure is 1.5 times the differential pressure i.e.: TopGear BLOC-line has the hydrostatic test pressure at 24 bar (86-100 15 bar).
3.7.2 The sound level of the pump unit The sound level of the drive (motor, transmission, . . .) must be added to the sound level of the pump itself to determine the total sound level of the pump unit. The sum of several sound levels must be calculated logarithmically.

3.17 Installation 3.17.1 General This manual gives basic instructions which are to be observed during installation of the pump. It is therefore important that this manual is read by the responsible personnel prior to assembly and afterward to be kept available at the installation site. The instructions contain useful and important information allowing the pump/pump unit to be properly installed.
3.17.2.4 Indoor installation Locate the pump so that the motor can be vented properly. Prepare the motor for operation according to instructions provided by the motor manufacturer. When flammable or explosive products are pumped, a proper earthing should be provided. The components of the unit should be connected with earthing bridges to reduce the danger arising from static electricity.
3.17.4 Shaft rotation for pump without safety relief valve The shaft rotation determines which port of the pump is suction and which is discharge. The relation between the shaft rotation and the suction/discharge side is indicated by the rotation arrow plate attached at the top cover of a pump without safety relief valve. 1.
Page 29
The small arrows 2 and 3 indicate the flow direction of the pumped liquid. Always make sure that shaft rotation corresponds with the position of the discharge and suction ports and the direction indicated by the rotation arrow plate. If the shaft rotation is correct in relation to the port position but different from the direction indicated by rotation arrow plate, the safety relief valve must be disassembled and turned around by 180°.
3.17.6 Suction and discharge pipes 3.17.6.1 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.
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.
3.17.7.2 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).
3.17.9 Guidelines for assembly When a bare shaft pump is delivered, the assembly with drive is the responsibility of the user. The user also must provide all necessary devices and equipment allowing a safe installation and commissioning of the pump. 3.17.9.1 Transport of pump unit •...

3.18 Instructions for start-up 3.18.1 General The pump can be put into service when all arrangements described in chapter 3.17 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.
3.18.4 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.
3.18.5 Start-up When the pump is to be put into service the following checklist and procedure must be observed: c Pump is filled with liquid. c Pump is sufficiently preheated. c Suction and discharge valves are fully open. c Start the pump for a short while and check the direction of rotation of the motor. c Start the pump and check suction of liquid (suction pressure).
3.19 Trouble shooting Symptom Cause Remedy No flow Suction lift too high • Reduce difference between Pump not priming pump and suction tank level. • Increase suction pipe diameter. • Reduce length and simplify suction pipe (use as few elbows and other fittings as possible). Also see section 3.17 Installation.
Page 39
Symptom Cause Remedy Not enough capacity Viscosity too low 17 • Increase pump speed. Attention! Do not exceed maximum speed and check NPSHr. • If necessary, install a larger pump. • If pump is heated by means of heating jackets or electrical heating, reduce the heating input.
3.19.1 Instructions for re-using and disposal 3.19.1.1 Re-use Re-use or putting the pump out of service should only be undertaken after complete draining and cleaning of the internal parts. Note! When doing so, observe adequate safety regulations and take environmental protection measures.
3.20 Maintenance instructions 3.20.1 General This chapter only describes operations that can be performed on-site for normal maintenance. For maintenance and repair requiring a workshop contact your local supplier. • Insufficient, wrong and/or irregular maintenance can lead to malfunctions in the pump, high repair costs and long-term inoperability.
• Keep the surface of the pump as clean as possible. This simplifies inspection, the attached markings remain visible. • Make sure cleaning products do not enter the ball bearing space. Cover all parts that must not come into contact with fluids. In case of sealed bearings, cleaning products must not attack rubber gaskets.
3.20.3.1 Nuts and bolts Nuts and bolts showing damage or parts with defective threading must be removed and replaced with parts belonging to the same fixation class as soon as possible. • Preferably use a torque wrench for tightening. • For the tightening torques, see table below.
3.20.4 Front pull-out The TG BLOC pumps also have a front pull-out system. To remove liquid residues or to check the idler bearing for wear, the pump cover can be pulled out from the pump housing without disconnecting suction and discharge pipes.
