3 ALLWEILER . 1 General Abbreviation Application and range of utilization The abbreviation of the screw pump is set up according The inside bearing screw pumps of type series to the following schema, and is engraved on the type are three screw, rotary positive displace- plate. ment pumps for lubricating liquids. The liquids must not contain any abrasive particles nor chemically attack the Example: pump materials. Due to a modular system, the pumps may be designed as cartridge unit pumps, horizontal foot mounted Series pumps, flange mounted pumps as well as vertical SM H 40 E R 46 U 2 E W2 plinth mounted pumps. Performance data Type series The exact performance data applicable to the pump can be taken from the order data sheet and/or Design H = Horizontal foot pump, acceptance test report, and are engraved on the name plate.
4 GH = Horizontal foot pump, The pressure data indicated there apply only to branches U turn approximated static pressure load. In the case of E = Cartridge unit pump for dynamic alternating pressure load, consult the H and GH pumps manufacturer. F = Flange pump, Warranty GF = Flange pump, Our warranty for shortcomings in the supply is laid branches U turn down in our delivery conditions. No liability will be S = Plinth pump, undertaken for damages caused by non compliance GS = Plinth pump, with the Operating Instructions and service conditions. branches U turn If at any later date the Operating conditions change ( EF = Cartridge unit pump for different fluid conveyed, speed, viscosity, temperature F, GF, S and GS pumps or supply conditions), it must be checked by us from case to case and confirmed, if necessary, that the pump Size is suited for those purposes.
5 Where no special = theoretic delivery in [l/min] agreements were made, pumps supplied by us may, with normal pitch and during the warranty period, only be opened or varied by 1450 1/min us or our authorized contract service workshops;. Type of driving spindle otherwise our liability for any defects will cease. Testing Direction of screw pitch R = right (serial design) Prior to leaving our factory, all pumps are subjected to a L = left thorough test run and performance test on the test stand. Only properly Operating pumps, achieving the Angle of screw pitch [degrees] performance assured by us, leave the factory.

Shaft seal uncooled/unheated Availability Shaft seal As a matter of principle, we recommend stocking 2 = Soft packing replacement pumps and withdrawable units (hydraulic 3 = Two shaft seal rings action system) where the supplied pumps are a 4 = Three shaft seal rings decisive factor in maintaining a production or delivery = Mechanical seal = Mechanical seal process. In this way downtimes can be avoided, or reduced to a minimum.

ALLWEILER . 2 Safety These Operating Instructions contain basic safety Dangers in the event of non compliance with Instructions for installation, operation and safety Instructions Maintenance . It is therefore essential that they are read Failure to comply with the safety Instructions may result by fitters and all specialist staff and customer personnel in danger to persons, and place the environment and prior to installation and start up. They must always be the machine at risk. Non compliance with the safety kept at hand at the place of installation. Instructions may lead to the loss of any claims for damages.
8 The special safety Instructions contained in the other Non compliance may relate to the following dangers: chapters must be observed in addition to the general safety Instructions in this chapter. S Failure of important functions of the plant Marking of Instructions in the Operating S Failure of specified methods for Maintenance and Instructions servicing The safety Instructions contained in these Operating Instructions which represent a danger to personnel if S Danger to persons resulting from electrical, not complied with are specially marked by the general mechanical and chemical effects danger symbol: S Danger to the environment resulting from leakage of hazardous substances Responsible working practices The safety Instructions contained in these Operating Warning symbol Instructions , current national accident prevention as per DIN 4844 W9 regulations, as well as internal working, Operating and safety rules of the customer, must be observed.
9 Warning of danger from electric voltage is given as Safety Instructions for the user/operator follows: S Hot or cold parts representing a danger must be protected against accidental contact on site. S Protection against accidental contact for moving parts (such as the coupling) must not be removed Warning symbol while the machine is in operation. as per DIN 4844 W8. S When Operating pump aggregates in a dust laden environment ( milling, chipboard manufacture, Instructions which are essential to avoid endangering bakeries), the surfaces of the pumps and motors the machine and its functioning are marked by the word must be cleaned at regular intervals, depending on local conditions, in order to maintain the cooling ATTENTION effect and eliminate the possibility of spontaneous combustion.
10 Refer also to explosion protection regulations (ZH 1/10). Instructions affixed directly to the machine such as S Leakage ( from the shaft seal) of hazardous S Directional markers substances being handled, such as explosive, toxic or hot materials, must be discharged such that no S Signs for fluid connections danger to persons or the environment is created. Legal regulations must be observed. must always be observed and maintained in fully legible condition at all times. S Dangers from electrical energy must be eliminated. For details in this regard, refer to VDE and local Personnel qualification and training power company regulations.
