1. General
Operating Instructions for Screw Pumps, Type Series SD.•. G9
Drwg.No. 629 0005 SaSE Page 1 of 4 paqes Date 12/10/82
The ALLWEILER screw pumps of type series SD are self-priming three-screw types of positive displacement pumps for handling media with lubricating properties. They were especially designed for being used in hydraulic systems.
Depending upon the viscosity of the fluid to be pumped, the pumps can be used up to a max. d eLf,very pressure of 210 bars.
The type series comprises 4 sizes each of which is designed with several screw pitches thus allowing a very close adaptation to required delivery quantities ranging from 10 - 160 limine
The pumps may be mounted either horizontally or vertically.
The pump drive may ' be by a flexible coupling only; great radial forces must not act on the shaft journal of the pump.
2. Design
The hardened and ground screws run in a very inherently stable casing of an artificially aged aluminum alloy in evacuated screw bearing surfaces thus allowing very good running properties and consequently a long service life of the pumps to be reached.
Both, the driving screw and the working screws are hydraulically balanced. For the working screws, this is achieved by directing the operating pressure through bore holes into the balancing bushes 8. Thus, the operating pressure is
• - - I admitted to the end faces of the working screws on the delivery and suction side, hydraulically caused axial forces cannot be incurred. For the driving screw to be hydraulically balanced, the diameter of the bushing safely shrunk onto the screw is measured so that the pressureloaded end faces are of equal size towards both, the suction and coupling side. In this way, the forces cancel each other. The bushing safely shrunk onto the driving screw and running in bearing ring 10 serves for both, the radial and axial bearing of the screws; at the same time, the gap between shrunk-on bushing and bearing ring separates the pressure chamber from the stuffing box chamber.
3. Mode of operation
Through the suction connection, the medium is pumped into the suction chamber of the pump from where the fluid flows into the screw chambers continuously formed by the rotary motion at the screw end on the suction side .

Operating Instructions for Pumps, Type Series SD... G9
Screw Drwg. No. 629 0005 SOSE Page 2 of 4 pages Date 12/10/82
Due to the rotary motion advancing, the chambers filled with the fluid to be pumped travel from the suction side to the delivery side during which travel the closed chamber volume does not change. At the screw end on the delivery side, the chamber opens towards the delivery chamber. The medium is steadily pushed out into the delivery chamber entering the delivery line through the delivery connection. Because of the screw length as fixed for this series, there are always several chambers between the delivery and suction side. They provide for the sealings between the suction and operating pressure of the pump. Due to the gap loss from chamber to chamber, the same pressure difference comes up inevitably between all neighbouring chambers. Thus, the pressure is gradually built up over the screw length from the pressure in the suction chamber to the prevailing operating pressure. The low rate of pressure rise connected therewith is one of the causes of the low pulsation and the especially low sound pressure level of the screw pump. Moreover, a low rate of pressure rise has a favourable effect on the lifetime of hydraulic fluids.
The throttling space formed by bearing ring 10 and the driving screw is a gap sealing between deliv~ry and stuffing box chamber. Due to the throttling effect, the amonnt of leakage flowing through this gap reaches the stuffing box chamber;' pressureless, from where it-is return~d through bore holes into the suction chamber.
The amount of leakage in the stuffing box chamber lubricates simultaneously the shaft sealing ring 183 dissipating the generated frictional heat to the suction chamber.
4. Pump mounting
4.1 By means of two screws, the pump is fixed by way of the ( front flange whose dimensions correspond to SAE Standards.
The socket for the spigot must be designed so that exact alignment of pump and motor is reached during assembly requiring no additional adjustment.
4.2 Prior to fitting the coupling, same must be heated up to at least 80 0 Fixing the coupling in cold condition may lead•
to destruction of the pump.
4.3 Attend to sufficient distance between the shaft ends of pump and motor which should be approx. 4 mm.
4.4 Following the assembly of pump and motor, the unit must allow of manual turning at the coupling. It is recommended to check the coupling alignment at least with the straightedge.;
4.5 Suction and delivery lines must be designed so that during standstill of the unit the pump cannot run empty. Thus, dry operation of the pump after a prolonged standstill period is prevented.

Date 12/10/82
4.6 Prior to being connected to the pump, all pipe lines, gate valves and the oil tank must be thoroughly cleaned and flushed resp. Mounting residues such as welding beads, steel chips and the like would destroy the pump internals.
4.7 Suction and delivery lines ~ust be connected stress-free. Suitable routing of the pipe line must secure that no material- forces are transmitted onto the pump, not even with the lines being heated.
The pump must not be used as a fixed point for the pipe lines.
5. Start-up
5.1 Prior to the first start-up, the motor must be checked for proper sense of rotation.
5.2 Prior to the first start-up, the pump must be filled with fluid to be pumped. Pumps with a supply line or those used as oil submerged pumps are filled automatically.
Filling of the pump prior to the first start-up prevents dry operation which would result in pump destruction.
5.3 Open suction and delivery gate valves. '-""'" .' , : ,,: ,~,
5.4 The pump must first be started without pressure.
5.5 Pressureless operation must be maintained until the entire unit has been vented. Open appropriate venting screws in the unit. Incase of horizontal pump installation with overhead pipe line connections, and in case of vertical installation, the pump is vented automatically.
5.6 The unit having been vented, the pump may be run to the operating pressure.
6. Dismounting· of pump ,.
6.1 The pump can be dismounted by slackening the two fastening screws.
6.2 Draw off coupling half from the driving screw. The coupling half must be heated so as to allow withdrawal without destruction of the pump components.
6.3 Remove key 290.
6.4 Slacken screw connection 201 and remove pump cover on the end side 4.
6.5 Remove balancing bushes 8 from the balancing pin of the working screw, the working screws can now be drawn out of the casing.

6.6 Slacken screw connection 200 and remove pump cover on the driving side 3 with radial seal ring 183.
The radial seal ring should be removed from the cover only if the seal ring needs to be replaced. For these purposes remove circlip 250 and support disk 260 from the cover.
6.7 Screw set 12, i.e. driving screw and working screws can now be withdrawn from the casing. During mounting, the screws are match-marked at the works by -means of colour dots. The colour marking is provided at the profile end on the suction side. The colour marking having faded, appropriate marks have to be provided prior to disassembly of the screw set. During mounting, the screw set must be re-assembled in the same order of succession. The colour marking for all three screws must point in one direction.
6.8 If necessary, bearing ring 10 can now be withdrawn.
7. Mounting of disassembled pump
7.1 Prior to assembling the components, absolutely see to it that all parts are free from dirt and greasy pa~ticles.
Assembly of the pump is performed in inverse oreer than described for dismounting.
7.2 When mounting screw set 12 absolutely see to it t'lat the colour marks of the three screws should point in une direction. Prior to being mounted, screw set 12 must be well oiled with clean oil.
7.3 Prior to mounting the shaft seal ring, the front part of the driving screw must be well oiled so as to avoid any damages to the seal lip during fitting.
8. Maintenance
Lubrication of all sliding parts is provided by the pumped fluid thus being completely maintenance-free.
9. Spare parts
9.1 The spare parts provided are those parts in the spare parts list marked with an asterisk.
9.2 When ordering spare parts, always quote the pump number hammered in the rating plate of the pump.
9.3 For mounting and repair purposes, trained specialists will be at your disposal, if need be.
