3 Introduction MTS MTS This data booklet deals with MTS pumps. see fig. 1 MTS pumps are screw pumps designed for pumping of cooling lubricants and cutting oils for machine tool applications. The pumps are designed to be mounted on top of tanks with the pump immersed in the pumped liquid. Grundfos MTS pumps come with various pump sizes and screw pitches to provide the flow, pressure and length required. The pumps consist of two main components: The motor and the pump unit. The motor is a Grundfos standard MG motor designed to EN standards. The pump unit consists of optimised hydraulics, various types of connections, a motor stool and various other parts.

6 General description MTS Main applications MTS pumps are an important part of modern metal machining centres, transfer lines and grinding and deep-hole drilling machines. Application Transfer of well, conditionally or poorly lubricating abrasive liquids in metal working or process engineering, such as cutting, grinding and deep-hole drilling oils, oilin-water emulsions and cooling lubricant solutions. The pumped liquid must not attack the materials. Permissible cooling lubricants: Solutions (inorganic substances in water; organic and synthetic substances in water) Emulsions (oil-in-water, oil content 2 % to %) Cutting and grinding oils (without additives; with polar physically acting additives; with mildly acting, lubricating film forming additives; with polar and mildly acting additives; with active, chemical additives; with polar and active additives) Product range Fig. 1 Princip skitse 1 Machining center 2 MTS high presure pump 3 Drilling tool 4 Work piece 5 Filter pump TM Range MTS MTS MTS MTS 1 MTS 2 MTS 2 MTS 4 Hz Flow range [l/min] Motor power P2 [kw] Hz Flow range [l/min] Motor power P2 [kw] General data Max. temperature [ C] Max. differential pressure (emulsion) Max. differential pressure (oil) Max. inlet/suction pressure (DQ version) Max. inlet/suction pressure (D8.6 version) Pipe connection Suction (DQ version) G 1¼ G 1¼ G 2 G Suction (D8.6 version) SAE 1½" SAE 1½" SAE 2" SAE 2" SAE 2½" SAE 3" SAE 4" Discharge pipe thread G 3/4 G 3/4 G 1¼ G 1¼ Discharge flange SAE 1" SAE 1" SAE 1½" SAE 1½" SAE 2" SAE 2½" SAE 3" Installation length [mm] Shaft seal DQ (seal ring) D8.6 (mechanical seal) 6

7 General description MTS Type key Example MTS (E) - R 46 D 8.6 Type range With integrated frequency converter Frame size-max. pressure (bar) Spindle sense of gradient (R = right) Spindle pitch angle in degrees Construction feature D = External ball bearing, shaft seal unheated, uncooled Shaft seal/connections Q = Shaft seal ring/axial inlet, pipe thread as standard 8.6 = Mechanical shaft seal/radial inlet, SAE as standard Construction Three-screw, self-priming, flange-mounted pump (DIN ISO 19-2) with special surface-hardened drive and idler screws. The idler screws are hydraulically driven, and the axial thrust is completely neutralised hydrostatically. The drive screw is fixed in position with external, permanently lubricated groove ball bearing. The large overall length with its many chambers results in little surface pressure, low pressure differences and thus reduced wear. The rotor housing has been optimised to ensure maximum resistance to wear. The material used is specially hardened grey cast iron (EN-GJL) that is part of a special safety concept. The housing surface in contact with the screws has a ceramic-like hardness. Additionally, unlike with other materials (such as SiC), wear, shocks, vibration or aeration cannot lead to sudden failure of the pump unit. Construction and materials result in little wear, good controllability and high efficiency. Motor MTS pumps are fitted with a totally enclosed, fancooled, 2-pole Grundfos standard MG or a Siemens motor with principal dimensions according to EN and IEC standards. Electrical tolerances according to EN 34. Motor protection MG motors Three-phase motors must be connected to a motorprotective circuit breaker in accordance with local regulations. Three-phase Grundfos and Siemens motors from 3 kw and upwards have a built-in thermistor (PTC) according to DIN 482 (IEC 34-11: TP 211). Terminal box positions As standard, MTS pumps have their terminal box mounted in position 12 o'clock of the pump; however, other positions are possible. Position 6 o clock Position 9o clock Fig. 2 Terminal box positions Position 12 o clock Standard Ambient temperature kw motors (EFF2, MG): Max. + C kw motors (EFF1, MG Max. + C - kw motors (EFF1) Max. +55 C Position 3 o clock If the ambient temperature exceeds above maximum values or if the motor is located metres above sea level, the motor output (P2) must be reduced due to the low density and consequently low cooling effect of the air. In such cases, it may be necessary to use a motor with a higher output.

8 General description MTS Overload protection The pump has no pressure-relief valve. Thus the overload protection must be provided in the control system or with a pressure-relief valve. pressure line to system Important! Shaft sealing/connections Design DQ Shaft sealing with shaft seal ring. Inlet pressure up to 1 bar. Axial inlet with pipe thread connection (DIN EN ISO 228-1). Radial high-pressure discharge flange according to SAE J518C. MTS to 1 additionally with pipe thread connection (DIN EN ISO 228-1). pressure relief valve pump suction from tank Fig. 4 Overload protection Sound pressure level MTS construction design allows gentle, even, virtually pulsation-free and low-noise pumping. The noise emission lies between 56 and 74 dba and depends on speed, pump size and installation. MTS pumps operate significantly quieter than rotary lobe and centrifugal pumps with comparable performance. Measuring conditions: Backflowline to tank Distance to the pump: 1 m Operation: Cavitation-free Motor: IEC standard motor Tolerance: ± 3 db.

40 NPSH curves MTS NPSH curves for MTS pumps The performance curves refer to liquids without any air enclosed and show the beginning of aeration. For this reason, a safety margin of.5 m must be added to the NPSH value taken from the curve. For liquids with air inclusions (undissolved air), an additional value must be added to the NPSH value derived. When dealing with critical conditions in your plant, always consult Grundfos. Maximum allowable air content Emulsion: % Oil: 7 %. Spindle 46 TM Example Given: Wanted: Solution: Size 1-46 Speed n = 2 min 1 Viscosity ν = mm 2 /s NPSH required. NPSH taken from curve = 5.4 m H + safety margin.5 m = 5.9 m H.

42 Pumped liquids MTS List of pumped liquids The composition, oil content (ability to provide lubrication) and cooling effect of the liquid determine the pump maintenance intervals and maximum permissible performance data. Cooling lubricants according to DIN are divided into three groups according to water and oil content. Pump also pump cooling lubricants with a very low lubricating effect, but very high cooling performance ( main group ). Cooling lubricant main group Subgroup Effect at the processing spot L Solutions E Emulsions S Petroleum-based cutting and grinding oils (natural and synthetic) Solutions of inorganic materials in water Solutions, dispersions of organic (synthetic materials in water) Oil-in-water emulsions (Oil content E 2 % to E % Cutting oils without additives (pure) Cutting oils with polar (physically effective) additives Cutting oils with mild-effect (lubricating film forming) EP additives Cutting oils with polar and mild-effect EP additives Cutting oils with active (chemical) EP additives Cutting oils with polar and active EP additives Higher cooling effect, lower lubricating effect Cooling-lubricating effect Higher lubricating effect, lower cooling effect Better surface adhesion provides protection against corrosion Higher temperature and pressure resistance Filtration To reach an acceptable pump life, we recommend the cooling lubricants be filtrated to following cleanness classes according ISO 46/99. The recommended cleanness class depends on pumping pressure and abrasive class 1 to 7. There are process examples for abrasive classes given below the table. The additional specifications to filter mesh and mass proportion are guide values for orientation. Decisive factor is the cleanness of the liquid indicated by the cleanness class. To avoid damage by coarse particles, it is advisable to use a filter mesh of 65 μm (nominal, two dimensional) and finer.
