Screw Pumps Series SPF/M MagDrive

Application For the delivery of fuel oils, hydraulic oils or other lubricating liq-uids. The fluid media must not contain any abrasive particles nor attack the pump materials chemically.

Main fields of application SPF/M-pumps operate as transfer, booster and burner operation pumps in fuel oil engineering, as transfer and filling pumps in tank farms as well as lube-oil pumps in any industrial branches. They are moreover used for pressure generation in oil-hydraulic plants of all kinds.

Design/Construction Self-priming three-screw type of pump with internal bearing, without shaft sealing due to magnetic clutch. The pump is her-metically sealed due to the can of the magnetic clutch.

The hardened and ground screws run in an exchangeable cas-ing insert.

The driving screw is hydraulically balanced. The end-side pump cover absorbs the axial thrust of the working screws. Their drive is hydraulic. The thread flanks merely transmit the torque result-ing from the liquid friction. Thus, the thread flanks are practically stress-free and not subject to any wear. All sliding parts are lu-bricated by the delivery medium being within the range of full liq-uid friction.

The radial and axial bearing of the driving screw with pump size 20 is by the balancing piston guided in the bearing ring, with pump size 40 by a groove ball bearing.

Magnetic clutch and suction chamber are interconnected by way of a return gallery. Thus, the liquid circulates in the clutch cham-ber and leads away the heat, caused by eddy currents.

The delivery is carried out as complete unit. A pump bracket with mounting foot carries out the connection pump/driving motor.

Operation The three spindles build due to their special profiling of the thread flanks, an axial and continuous shifting by rotation of the spindles from the suction to the pressure side. Despite the spin-dle rotations no turbulences occur. Consistent chamber volume excludes squeezing.

Noise/Pulsation The structural design and operation of the screw ensure a very low noise level and an almost pulsation-free delivery.

Twin units For all plants requiring stand-by pumps, twin units are supplied. See descriptive literature VM 863.

Performance data Capacity Q 10 I/min up to 110 I/h

Temperature of the fluid pumped t up to 150 °C

Inlet pressure pz up to 6 bar

Pump outlet pressure pd up to 40 bar

Viscosity range v =2 up to 750 mm²/s

Delivery flange DNd=20 up to 25 mm

With n = 2900 1/min For the attainable delivery pressure as a function of viscosity and speed, pleas

refer to the individual characteristics. The pressure data only apply to nearly static pressure load. With dynamic pressure change load, please inquire.

Pressure relief valves As an overload protection, installed in each pump is a pressure relief valve, which, with all designs, is set at a response pressure approx 10% above the operating pressure.

In case of different response pressures are requested, it must be indicated in the order.

For design with filter only

Installation SPF/M-pumps may be mounted in any position. For safety pur-poses, the arrangement with “motor downwards” is not admissi-ble.

Drive Drives of the following type are normally provided:

Surface-cooled three phase squirrel cage induction motors, IM V1 type of construction; enclosure IP54 according to IEC Stan-dards, class B insulation, performances and main dimensions according to DIN 42677.

Motors rated for 50 Hz may without any change also be oper-ated also from 60 Hz supply systems, speed and performance will change as follows:

Magnetic clutch A connection flange to the drive-side of the screw pump fixes the magnetic clutch. The driving screw of the pump is stiffly con-nected with the rotor of the magnetic clutch.

Non-contact transmission of torque between driving motor and pump due to the magnetic flux lines between inner and outer ro-tors.

Filter As a protection against contaminations, the pumps can be sup-plied with a filter casing with incorporated radial screen filter (surcharge). Filter mesh size 0,4 mm.

A pressure vacuum gauge included in the scope of supply indi-cates the pressure behind the filter. Thus, the pressure loss in the filter can be determined and an inadmissible contamination realized.

Electric heating (only per order) In case of design with filter, heating shell may be provided for fil-ter heating (surcharge).

Pump size Connection for Heating capacity

SPF 20 230 V 205 W SPF 40 230 V 265 W

The heating capacity is rated so that with an initial temperature of 20°C, a minimum heating-up time of 120 min. is required. In case of lower temperatures (below 0°C), an appropriately longer heating up time must be expected. The heating is not suited to achieve, during operation, a marked temperature increase of the fluid to be pumped.
