1 Screw umps Application For the delivery of fuel oils, lube oils, hydraulic oils or other lubricating liquids. The fluid media must not contain any abrasive particles nor attack the pump materials chemically. Main fields of application SF 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 Self-priming three-screw type of pump with internal bearing. The hardened and ground screws run in an exchangeable casing insert. The driving screw is hydraulically balanced. The axial thrust of the working screws is absorbed by the endside pump cover. Their drive is hydraulic. The thread flanks merely transmit the torque resulting from the liquid friction. Thus, the thread flanks are practically stress-free and not subject to any wear. All sliding parts are lubricated by the delivery medium being within the range of full liquid friction. The radial and axial bearing of the driving screw with pump size and is by the balancing piston guided in the bearing ring, with pump size by a groove ball bearing. A maintenance-free mechanical seal is provided as the shaft sealing. Sealing chamber and suction chamber are interconnected by way of a return gallery. Thus, independently of the delivery pres-sure at the shaft sealing, only the suction pressure becomes effective. Complete units being supplied, the connection pump/driving motor is by a pump bracket with mounting foot. Operation Owing to a special profiling of the thread flanks, the three screws from sealed chambers the contents of which are axially and completely continuously shifted from the suction to the pump side of the pump as the screws turn. There will be no turbulence in spite of the screw rotation. The constant chamber volume excludes squeezing. Noise/ulsation The structural design and operation of the screw pump 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 33. Shaft sealing By means of a maintenance-free mechanical seal of the unbalanced type. Material design: Rotating seal ring Tungsten carbide, Co-binder Stationary seal ring Tungsten carbide, Co-binder Joint ring FM Spring CrNiMo steel Metal parts Cr steel erformance data Capacity up to 112 resp. 67 I/h Temperature of the fluid pumped t up to 1 C Inlet pressure p z up to bar ump outlet pressure p d up to bar Viscosity range ν 3 up to 7 mm²/s Delivery flange DN d up to 2 mm With n = 29 1/min and = 7 mm 2 /s With higher temperatures, please inquire. For the attainable delivery pressure as a function of viscosity and speed, please refer to the individual characteristics. The pressure data only apply to nearly static pressure load. With dynamic pressure change load, please inquire. ressure 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. % above the operating pressure. In case different response pressures are requested, same must be indicated in the order.

2 Installation SF pumps may be mounted in any position. For safety purposes, the arrangement with "motor downwards" is not admissible. Drive/Coupling By way of an intermediate bracket, electric motors of the most varied designs or other prime movers can be connected with the pumps. Normally, the following are provided: Surface-cooled three-phase squirrel-cage motors, IM V1 type of construction, enclosure I4 according to IEC Standards, class B insulation, performances and main dimensions according to DIN Motors rated for Hz may without any change also be operated from 6 Hz supply systems, speed and performance will change as follows: Motor Connection Conversion factor wound for to 6 Hz for operation with 6 Hz Hz...V...V Speed erformance 2 V 2 V 1,2 1, V V 1,2 1, V 46 V 1,2 1,1 46 V 46 V 1,2 1, The power transmission is by a flexible coupling. Additional radial forces must not act upon the driving screw. Filter As a protection against contaminations, the pumps can be supplied with a filter casing with incorporated radial screen filter (extra price). Filter mesh size,4 mm. A pressure vacuum gauge included in the scope of supply indicates the pressure behind the filter. Thus, the pressure loss in the filter can be determined and an inadmissible contamination realized Electric heating Designs with filters can be provided with heating shells for filter heating (extra price). ump size Connection for Heating capacity SF SF SF 2 V 2 V 2 V 16 W W 26 W The heating power is rated so that with an initial temperature of C, a minimum heating-up time of 1 min. is required. In case of lower temperatures (below C), an appropriately longer heating-up time must be expected. The heater is not suited for achieving, during operation, a marked temperature increase of the fluid to be pumped Abbreviation system SF R 38 G 8.3 F E W Series Size = theoretical delivery flow at 1 1/min and 46 pitchangle Direction of screw pitch R = right Angle of screw pitch (degrees) Type of bearing G = internal slide bearing U = internal groove ball bearing Shaft sealing by unheated uncooled mechanical seal Ausführung mit Filter 1 Ausführung mit elektrischer Beheizung des Filtergehäuses 1 Werkstoff-Ausführung 1 available at extra charge NSH erf.
