Quick Reference Chart
STANDARD PUMP — The SV pump is a pressure compensatedvane pump and is available in four basic displacements: one, two,four and eight cubic inches. This bulletin covers the model SV-40(four cubic inch displacement) and a variation of it which isdimensionally the same.
TWINVANE PUMP — The TV-40 (TWINVANE) pump is astandard pump with internal changes which allow it to operate oneither high water content fluids (HWCF) or petroleum fluids. Itprovides an equivalent life on HWCF with only a slight reductionin volumetric and overall efficiency when compared to operationwith petroleum oil at the same pressure and rpm.
MAXIMUM INLET VACUUM AT SEA LEVEL –6 in. Hg (152 mm Hg)3 in. Hg (76 mm Hg) with fluids containing water
MAXIMUM CASE PRESSURE – 10 psi (0.7 bar) Case drain line should be full intended size (not reduced down).Case pressure spikes can be minimized by using as straight anddirect a path to tank as possible. Other drain lines should not beconnected to the pump drain line. Always terminate the drain linebelow the fluid level in the reservoir. Failure to do so will result inloss of pump prime approximately 30 minutes after it is shut downand possible introduction of air into the circuit. Case drain lineshould be routed to the opposite side of baffle in relation tosuction line.
CASE DRAIN FLOW – The values listed below are the averageflows which occur only when the pump is compensating. Whenthe pump is not compensating, the values are much lower.
300 in3/min (4.9 I/min) at 1000 psi (68 bar)400 in3/min (6.6 I/min) at 2000 psi (138 bar)
DRIVE SPEED RANGE – 750-1800 rpm (Consult factoryApplications Dept. for higher speeds)
MOUNTING – SAE C 2-Bolt Flange, side or rear ported.
ROTATION – Right hand and left hand rotation is available.Rotation is always determined when viewing the shaft end.
SEALS – (Buna N seals are no longer available. Viton seals arethe new standard) Buna N seals are compatible with petroleumoil, water glycol and water-in-oil emulsion. When using phosphateester, viton seals must be specified. Viton is compatible with all ofthe fluids mentioned.
FILTRATION – A 10 micrometer return line filter is recommendedfor increased pump life. If a suction strainer is used, it should notbe finer than 100 mesh (149 micrometer) when using petroleumfluids. The higher specific gravity of fire resistant fluids and thehigher vapor pressure of the water containing fluids will aggravatethe pump inlet conditions. If a suction strainer is used with thesefluids, the mesh must be coarser (60 mesh or 238 micrometer)than what is used with petroleum oil or the surface area increasedto reduce the pressure drop.
OVERHUNG LOAD – Radial and axial forces on the shaft are notrecommended. Pump and prime mover should be mounted with
shafts inline (coaxial) and connected with a flexible coupling.Consult factory Applications Dept. for applications with overhungload.
FLUID RECOMMENDATIONS – A premium quality hydraulic oilwith zinc complex anti-wear additives is highly recommended.Refer to BOSCH REXROTH publication 9 535 233 456,“Petroleum Hydraulic Fluids Recommendations” for a list of fluidswhich meat or exceed the BOSCH REXROTH lubricationrequirements.
To compensate for the reduced lubrication values of even thepremium quality water containing fluids (glycols and water-in-oilemulsions), it is necessary to limit system pressure and rpm to thevalues listed in the table below for an equivalent life.
Refer to BOSCH REXROTH publication 9 535 233 457 “FireResistant Fluids”, for further details on fluid selection. Fluidsuppliers should be consulted regarding proper fluid maintenancewhen using fire resistant fluids containing water.
TEMPERATURE – The temperature of the fluid in the reservoirshould not exceed 130°F (54°C). The pump will operate with oilat higher temperatures provided the viscosity of the fluid is withinthe recommended range. Under no circumstances should the oiltemperature exceed 160°F (71°C). When using fire resistant fluidscontaining water, the fluid temperature should not exceed 120°F(49°C) to prevent an excessive rate of water evaporation.
SCREW VOLUME CONTROL – The screw volume control is anadjustable stop which is used to reduce the maximum pump flowand is optional. Turning clockwise will reduce the flow in directproportion to the displacement of the adjusting screw. Duringinitial start-up, the flow setting should be at least 30% of themaximum pump flow.
SV-40 – 1/4 turn (90°) clockwise will reduce the flowapproximately 4 gpm (15.1 l/min) when the pump isdriven at 1800 rpm.
When a volume control is used to reduce the maximum flow of thepump, the horsepower required to drive the pump is also reduced.To determine the Input HP, use the following formula:
Input = gpm x psi + Deadhead HP at the compensator settingHP 1714

MOUNTING POSITION – Pump should be mounted with theshaft horizontal. Caution must be exercised to prevent end thrustfrom being applied to the shaft.
SHAFT ALIGNMENT – Shaft alignment should be within 0.003"total indicator reading. If the shafts are not properly aligned,increased mechanical noise from the unit will result.
START-UP – To insure priming on initial start-up, air in the pumpand inlet line must be allowed to escape. If the pump outlet isnormally blocked, it must be temporarily vented. This can beaccomplished by opening the valve, temporarily cracking a fitting,or installing an air bleed valve (refer to Bulletin J-34).
CONTROL OPTIONS – Many energy saving controls are availablein addition to the standard two-stage pressure compensator.Refer to Bulletin A-11 for performance, and dimensional data.
COMBINATION MOUNTING – To simplify multi-pump circuits,adapter kits are available to mount additional pumps incombination on the rear cover of the flange mounted (side ported)pumps. Refer to Bulletin A-14 for horsepower limitations, adaptersavailable, dimensional data, and How-To-Order.
PRESSURE COMPENSATING RANGE –TV-40 – 260-1000 psi (18-69 bar)
FLOW –23 gpm (100 I/min) at 1200 rpm and 100 psi (7 bar) 28.5 gpm (110 I/min) at 1500 rpm and 100 psi (7 bar)
Because of the low viscosity of HWCF, the internal leakage isgreater and will result in a slight reduction in flow in comparison topetroleum oil. Refer to the performance characteristics on page 5.
MAXIMUM INLET VACUUM AT SEA LEVEL –When using high water content fluids, a positive head is beneficialbut not necessary. The TV-40 can be used up to 12 inches (30cm) above the fluid level at altitudes to 2000 feet (610 m) abovesea level.
CASE DRAIN FLOW – The value listed below is the average flowwhich will occur when the pump is compensating at 1000 psi.When the pump is not compensating, the flow is much lower.
2.5 gpm (11.3 I/min) at 1200 rpm (HWCF)
DRIVE SPEED RANGE – 750-1500 rpm
ROTATION – Right hand only. Clockwise when viewing shaft end.
SEALS – Viton seals are standard.
SCREW VOLUME CONTROL – The screw volume control isstandard.
FLUID RECOMMENDATIONS – If a high water content fluid isused, please consult the factory Applications Dept. during thefluid selection process for current list of approved fluids. Thispump is not compatible with phosphate ester fluids.
NOTE: All of the specifications for the standard pump also pertainto the TWINVANE pump except those listed below.
