YUKEN PV2R12、PV2R13 Double vane pump
Specifications of YUKEN PV2R12 and PV2R13 Double Vane Pumps
YUKEN PV2R12 and PV2R13 double vane pumps are composed of two single PV2R series vane pumps integrated in a single housing, driven by a common shaft. They are equipped with one suction port and two discharge ports, which can supply output flow to two separate circuits respectively[3][5]. The detailed specifications are as follows:
1. PV2R12 Double Vane Pump
| Specification Items | Details |
|---|---|
| Nominal Displacement | Small volume pump: 6, 8, 10, 12, 14, 17, 19, 23, 25, 31 cm³/revLarge volume pump: 26, 33, 41, 47, 53, 59, 65 cm³/rev[5][6] |
| Maximum Operating Pressure | Anti-wear petroleum base oils: 21 MPa (small & large volume pumps)R&O petroleum base oils: 16 MPa (small volume pump), 14 MPa (large volume pump)Anti-wear water glycols: 16 MPaOrdinary water glycols: 7 MPaSynthetic phosphate esters: 16 MPa (small volume pump), 14 MPa (large volume pump) |
| Shaft Speed Range | Petroleum base oils: 750 – 1800 r/min (minimum – maximum)Water-containing fluids: 750 – 1200 r/min (minimum – maximum) |
| Mounting Type | L: Foot mounting; F: Flange mounting |
| Rotation Direction | Standard: Clockwise (viewed from the shaft end); Counterclockwise rotation is available on request |
| Weight | Flange mounting: 25 kg; Foot mounting: 29.3 kg |
| Special Notes | 1. The sum of input power of small and large volume pumps is limited by the shaft speed.2. For pumps with nominal displacement of 6 or 8 cm³/rev, the speed should be increased above 1450 r/min when the pressure exceeds 16 MPa.3. For pumps using phosphate esters, add “F-” before the model number (special fluororubber seals are required). |
2. PV2R13 Double Vane Pump
| Specification Items | Details |
|---|---|
| Nominal Displacement | Small volume pump: 6, 8, 10, 12, 14, 17, 19, 23, 25, 31 cm³/revLarge volume pump: 76, 94, 116 cm³/rev |
| Maximum Operating Pressure | Anti-wear petroleum base oils: 21 MPa (small & large volume pumps)R&O petroleum base oils: 16 MPa (small volume pump), 14 MPa (large volume pump)Anti-wear water glycols: 16 MPaOrdinary water glycols: 7 MPaSynthetic phosphate esters: 16 MPa (small volume pump), 14 MPa (large volume pump) |
| Shaft Speed Range | Petroleum base oils: 750 – 1800 r/min (minimum – maximum)Water-containing fluids: 750 – 1200 r/min (minimum – maximum) |
| Mounting Type | L: Foot mounting; F: Flange mounting |
| Rotation Direction | Standard: Clockwise (viewed from the shaft end); Counterclockwise rotation is available on request |
| Weight | Flange mounting: 45.6 kg; Foot mounting: 55.6 kg |
| Special Notes | 1. For pumps with nominal displacement of 6 or 8 cm³/rev, the speed should be increased above 1450 r/min when the pressure exceeds 16 MPa.2. For pumps with nominal displacement of 31 cm³/rev, the maximum operating pressure is limited to 16 MPa.3. For pumps using phosphate esters, add “F-” before the model number (special fluororubber seals are required). |
3. Common Specifications
- Structure: Two single PV2R series pumps combined in tandem, common shaft drive, single suction port, two discharge ports.
- Hydraulic Fluid Compatibility: Compatible with petroleum base oils, water-containing fluids, and synthetic fluids (phosphate esters, water glycols, etc.).
