Single- and Multi-circuit Pumps for Circulating and Hydrostatic Lubrication as Gear and Vane Pump Units, Reservoir Units Gear pump unit The pump units specified in this leaflet are lubricant delivery pumps without pressure relief fixtures and are designed for continuous operation in circulating and hydrostatic lubrication systems. Units with one to twenty lubrication circuits are available. Multicircuit gear pumps ensure a uniform delivery rate to individual feed lines and lubrication points against varying resistances. Multi-circuit pump These pump units may also be used for hydraulic tasks to the extent permitted by the pressure and viscosity ranges stated in the tables on the following pages. The drive is provided by a three-phase motor designed for arated voltage of 230/400 V to DIN IEC 38. Specify special voltages, if required, when ordering. The indicated delivery rate refers to an operating viscosity of 140 mm2/s at a back pressure of p = 5 bars. The permissible pressure and delivery rates vary with the viscosity. Pay attention to the respectively permissible viscosity! When using oils with viscosities outside the indicated permissible ranges (spindle oils and highlyviscous oils), please ask for further information. Please note that even standard oils may become extremely thin-bodied or highly viscous due to changes in temperature. Ambient temperature max. +40 °C Lubricant temperature 0 °C to +80 °C

Single- and Multicircuit Pumps Single-circuit flangemounted units with integral cast valve chambers – Circulating lubrication Type units for mounting separately from oil reservoir Type MF units for flange-mounting on oil reservoir Use a special sealed pump for horizontal flange-mounting of the unit beneath the oil level. Explanation of the hydraulic function Explanation of the structural differences Both versions (M and MF) have the same hydraulic function. With type M the long screw plug D1 blocks flanged port R2 of the return duct. The oil returning from the valves V and C1 flows via R1...

Single- and Multicircuit Pumps Two-circuit flange-mounted units, valveless – Circulating lubrication Units for mounting separately from oil reservoir or for flange-mounting on oil reservoir When a third gear is added to the pump, these units have asecond delivery circuit (see P2). Unlike single-circuit units M and MF described on page 2, these pumps are valveless (see changes in C2 and E4). Since there is no internal oil return, there are no structural differences of the kind specified on page 2 for M and MF. A special sealed pump must be used for horizontal flange-mounting of the unit in a...

Single- and Multicircuit Pumps Four-circuit units for operation with separate priming pump Unlike the multicircuit pumps specified on pages 7 and 8, the pumps shown in figures 18-22 are operated as distribution pumps. They require a priming pump, which is operated separately. (For a selection of priming pumps, see the tables below.) distribution pump (multicircuit unit) Filter It is advisable to filter the oil upstream of the distribution pump inlet. priming pump (single-circuit unit) = suction port (priming pump) = pressure port (priming pump) = pump inlet (distribution pump) = pressure...
