2 LM screw pumps 1 64 EN 2 rimary areas of use Machine tools Machining centers Central and decentralized coolant and preparation systems Booster stations Lubricant and hydraulic units Among other things Due to its wear-resistant design, the LM series is especially suitable for: Demanding applications involved in processing difficult to mill materials such as aluminium and stainless steel Various precision applications such as in the aerospace industry Grinding applications Media Fluids with lubricating properties such as il in water emulsions with at least 4 5 % oil Cooling und cutting oils For pure fluids without abrasive or long fibre components erformance The LM screw pumps are offered in various frame sizes Within one pump frame size, combination with various motors is possible; erformance adjustment in 1 bar increments is standard. The pump part combined with the required motor is the pump type. LM: Delivery pressures to p max. = 12 bar Delivery rates to max. = 67 l/min The performance data is applicable to viscosities ν to max. 2 mm 2 /s. erformance data for pressures greater than 12 bar on request. Installation and operation As immersion pumps, the pumps have a 4-hole connection flange with standard connection dimensions for vertical container installation (inside the reservoir). The immersion depth can be adjusted to fit the respective container sizes by attaching an intake tube. A foot flange is attached to the pump support for horizontal positioning beside the container (outside the reservoir). Note: All devices are only to be installed or mounted by a qualified person. The existing safety measures are to be taken into consideration. lease refer to our operating manual to avoid errors. Configuration and function Design features Spindles specially hardened Hydrostatic thrust compensation 6 7 Shaft sealing: Rotary shaft lip-type seal Mechanical seal Configuration of the LM pumps Screw housing specially hardened Guard ring for rotary shaft lip-type seal Rotary spindle guidance in suction area Leakage monitoring Installation outside the reservoir with foot flange and external leakage feed-back system ressure regulating valve: Frame size pole motor Regulated speed motor Standard ptional Drive (1) and pump unit are connected using a curved-tooth coupling (2) within the pump support. The pressure housing (4) contains the bearings for the drive spindle and its sealing. The LM is a self-priming positive-displacement pump. The medium is pumped by a set of spindles (5)in the screw housing. This consists of a drive spindle and two screw spindles. Rotation of the spindles causes the pumped medium to move continually and without pulsation axially from the suction opening (7) in the suction housing (6) to the pressure limiting valve (up to size LM17) (3) with pressure port. The special profile formation of the spindles generate sealed chambers with minimum medium backflow and a high level of effectiveness.

For pure fluids none abrasive or long-fibre components. Generally acceptable contamination: Max. solids content: 4 mg/l Max. grain Size:.5 mm ( µm) for machining (lathing, drilling, milling) Application specific values on request. Kinematic viscosity: 1 2 mm 2 /s; over 2 mm 2 /s on request. umping temperature: C bis +8 C Maximum admission pressure: For design with rotary shaft seal: 5 bar For design with mechanical seal: 1 bar Geodesic suction head max. 4 m Running dry and operation with closed pressure side is not permissible. As positive-displacement pumps, screw pumps have to be protected against overpressure on the system side using a pressure regulating valve. Switching-on frequency: The pumps should be used for continuous operation to the extent possible. If this is not possible due to the process, then the pump's constant flow rate should be regulated using a frequency converter or a regulating valve for example. Electrical specifications The drive motors adhere to the VDE standards as well as the European motor standards (DIN EN 34 1) and the CE label requirements. Designs adhering to standards outside of Europe such as CSA, UL or according to special requirements such as those in USA or Japan are possible. rotection class...

LM screw pumps with frequency converters An LM pump with integrated frequency converter enables optimum usage depending on the application. It adjusts the electrical output to the application's requirements and thus saves energy. Adjustment can be made to various operating points in the characteristics field to configure the pump ideally for the area of application. This adjustment can be made either smoothly or with defined increments as required. If needed, a single pump with a frequency converter can be used to accomplish the tasks of several pumps (without speed adjustment). Full separation of the motor from the pump allows integration of the speed adjustable operation for retrofitters as well. Advantages Huge output range ptimum adjustment to the respective machining process Universal adjustability of the pump speed through all pressure ranges Frequency converters work almost no loss and are entirely maintenance-free Regardless of voltage fluctuation in the power supply Speed adjustment ensures effective delivery rate and usage Economically convincing, energy efficient alternative to standard solutions High dependability Long service life uick and simple commissioning Convenient integration in machine control Compact design For further information, see page 2.
