2 "PVL" Series Single Pump - Type "PVL" Hydraulic Fluids / Instructions Hydraulic Fluids. Type of Hydraulic Fluids Petroleum ase Oils...Use R&O (Rust and Oxidation inhibitor) type oils or anti-wear type oils. (equivalent to ISO VG- or ) Note: Only Petroleum ase Oils can be used for hydraulic fluids.. Recommended Viscosity and Oil Temperature Viscosity ranging between - mm /s ( - SSU). Oil temperatures between /+ C ( - F) Use hydraulic fluids which satisfy the recommended viscosity and oil temperatures given above. Note that if the PVL pump is started at a low speed of 9 r/min, the maximum fluid viscosity is limited to mm /s (9 SSU).. Control of Contamination Contamination of hydraulic fluids results in pump failures and reduced pump lives. Carry out sufficient contamination control for hydraulic fluids and keep contamination level within NS class. lso, use a µm (-mesh) tank filter on the suction side and install it more than mm ( in.) away from the tank bottom. Instructions. lignment of Shaft Employ a flexible coupling whenever possible, and avoid any stress from bending or thrust. Maximum permissible misalignment is less than. mm (. inches) TIR and maximum permissible misangular is less than... Suction Set the suction pressure within - to + kpa (.9 in. Hg vacuum to +. PSIG) at the pump inlet. In addition, use suction pipes having the sizes shown in the dimensional drawings. If the pump is installed above the tank level, set the suction port more than. m (. ft.) below from the oil level.. Precautions at Starting t an initial operation or at an operation after a long rest, the pump may have difficulty in sucking up the fluid. In such cases, an air bleed valve should be installed beforehand on the discharge side (model No. ST- -, catalogue No. Pub. EC-.), or discharge air by slightly slackening the connection on the discharge side. t starting, operate the pump intermittently as far as possible with no load. For fluid viscosity at starting, see the item "Hydraulic Fluids" above. Other Precautions. If a PVL series single pump is used at speed below r/min, install the pump with the suction port upside so that the pump can suck up the fluid easily at starting. No.

6 T,T,F SERIES Fixed Displacement-Single, Double, Combination Up to MPa ( PSI), 9 cm /rev (. CU.IN./rev) Single Pumps These pumps are widely used as a source of hydraulic power. They combine stable performance and robust construction with a wide range of delivery rates. Pub. EC- Graphic Symbol Double Pumps Two single pumps, driven by a common shaft, have two discharge ports so that the output flow can be sup-plied to separate circuits. Graphic Symbols T T T F F Combination Pumps Consists of a double pump with either two relief valves, or one relief and one unloading and check valve incorporated within a common housing. The pressure of each pump can be independently adjusted. Remote control or high-low two-pressure control is possible. Graphic Symbols Relief-relief Type Relief-unloading Type Relief-relief Type CT CT CT CT No.

However, the specifications of the pumps such as maximum pump speed may be changed according to the type of hydraulic fluids to be used. For details, please refer to the specifications of the pump concerned. Hydraulic fluids (Table ) Type of Fluids Descriptions Petroleum ase Oils Use anti-wear type oils or R & O (Rust and Oxidation inhibitor) type oils (equivalent to ISO VG or ). Use phosphate ester type fluids. Synthetic Fluids When phosphate ester type fluid is used, prefix "F-" to the model number because the special seals (fluororubber) are required to be used. Water Containing Fluids Consult your Yuken representative in advance.. Fluid viscosity and temperature Use the hydraulic fluids which satisfy the recommended viscosity and oil temperature given in the Table below.

30 Single Pumps "PVR" SERIES Fixed Displacement- Single,Double Up to MPa ( PSI), cm /rev (. CU.IN./rev) Pub. EC- These pumps are of high pressure and high performance, which have been developed especially for low noise operation. To comply with a variety of applications including injection moulding machines, PVR series single pumps provide the output flow of such a wide range as from. to cm /rev (. to. cu.in./rev). The intergral driving parts of the pumps are combined into a kit form and available for supply as a cartridge kit. Therefore, the replacement of the driving parts can be done easily. Graphic Symbol Double Pumps These double pumps consist of two PVR seires single pumps combined in tandem within a single housing and driven by a common shaft. Single suction port and two discharge ports are provided so that the output flow can be supplied to separate circuits. Graphic Symbol No.

However, the specifications of the pumps such as maximum pressure and maximum pump speed may be changed according to the type of hydraulic fluids to be used. For details, please refer to the specifications of the pump concerned. Hydraulic fluids (Table ) Type of Fluids "PVR" Series Single Pumps "PVR" Series Double Pumps Petroleum ase Oils Synthetic Fluids Use anti-wear type oils or R & O (Rust and Oxidation inhibitor) type oils (equivalent to ISO VG or ). Use phosphate ester type fluids. When phosphate ester type fluid is used, prefix "F-" to the model number because the special seals (fluororubber) are required to be used. Standard pumps can be used without conditions. Water Water-Glycols However, if any type other than those in Table is used, the maximum operating pressure is limited.

Suction pressures Set the suction pressure at pump inlet port at the value given in the table below. Furthermore, use the pipes in the suction side having the diameter as indicated on the installation drawings. In case where the pump is installed on the tank or at the position higher than the tank top cover, the height of the suction port of the pump should be less than metre (. ft.) from the oil level {less than. metre (. ft.) in case of using phosphate ester fluids or water containing fluids}.

For details, please refer to the specifications of the pump concerned.. Precautions at starting t an initial operation or at an operation after a long rest, the pump may have difficulty in sucking up fluid. In such cases, an air bleed valve should be installed beforehand on the discharge side (model No. ST- -, Catalogue No. Pub. EC-.), or discharge air by slightly slackening the connection on the discharge side. t starting, operate the pump intermittently as far as possible with no load. For fluid viscosity at starting, see the item of "Hydraulic Fluids".. Other precautions If a pump is used at speed below r/min, install the pump with the suction port upside so that the pump can suck up fluid easily at starting. No.
