Sandvik 56024636 45cc piston hydraulic pump: Two pumps, numbers one digit apart, both listed for the same loader. One is 28cc, the other is 45cc. Order the wrong one and the machine runs at the wrong speed, or the pump won’t fit the circuit at all. If you’re researching the Sandvik 56024636 45cc piston hydraulic pump, the first job is to make sure you aren’t looking at its smaller sister. Advance Hydraulic Works works with hydraulic pump repair and supply from Delhi NCR, and this is how we’d go through it with you. What is the Sandvik 56024636 hydraulic pump? An Indian dealer’s pump list names it as a Sandvik 56024636 45cc Piston Hydraulic Pump, right next to a Sandvik 56024635 A10VO28 Axial Piston Hydraulic Pump. A factory listing shows both numbers in one list, noting that one is used in the Sandvik LH410 and the other is also listed as used in the LH410. So the picture is clear. Two related pumps, one 45cc and one 28cc, both tied to the same machine. The listing for the larger one doesn’t spell out the model, so check your nameplate. Sandvik 56024636 45cc piston pump: what the size tells you The sister pump is named as an A10VO28, a Rexroth variable axial piston pump. Rexroth’s data sheet describes the A10VO as a variable pump in swashplate design for open-circuit hydrostatic drives, with sizes including 28, 45 and 71. So a 45cc pump in the same family would likely be the A10VO45. That’s an inference from the sister pump’s name, not something the listing says, so confirm it from the plate. For series 31, Rexroth offers a nominal strain of 280 bar and a most of 350 bar. Series 52 is decrease: 250 bar nominal and 315 bar most for the identical sizes. So the series after the slash matters as much as the size. What the size difference does The two pumps differ a lot. At a drive speed of 1,500 rpm, the 28cc pump gives 28 × 1,500 = 42,000 cc a minute, about 42 litres per minute. The 45cc pump gives about 67.5 litres per minute. That’s roughly 61% more oil from one pump than the other, a 25.5 litres per minute gap. At 250 bar, hydraulic power is about 250 × 42 ÷ 600, around 17.5 kW for the 28cc pump, and about 250 × 67.5 ÷ 600, around 28 kW for the 45cc. A seller’s catalogue for the series 52 shows about 28 kW for size 45 at 1,500 rpm and nominal pressure, which agrees. This is illustrative arithmetic, not a spec sheet, so use your machine’s real drive speed. Why mix-ups happen Adjacent numbers look alike. Sellers copy descriptions from one listing to another. And some listings say only “hydraulic pump” without the size. So a buyer can send the wrong number and get a perfectly good pump that doesn’t fit the job. If the machine needs 67.5 litres per minute and gets a 28cc pump, it will move far slower than it should. If it’s the other way round, the circuit may be overfed, run hot and hit its relief valve. The method: number, size, series, plate Number. Confirm the exact Sandvik number and its neighbours. Size. Check the displacement on the plate: 45, not 28. Series. Read the series after the slash and its pressure rating. Plate. Photograph the plate for all codes and compare it with the listing. A worked example Say you order a pump described only as a Sandvik pump from the same family. It arrives, and the plate says size 28 where you needed 45. The pump is fine. The order was wrong. Before it gets that far, ask the seller four questions. What size is it? What series? What control and rotation? And can you show a photo of the actual plate? If the seller can answer all four, the chance of a mix-up drops to almost zero. If it can’t, ask whether it’s worth the saving. This is an illustrative scenario, not a quote. Implementation steps 1. the vintage pump, its nameplate and any tags earlier than elimination. 2. Write down the full code, which includes size, manipulate, collection and rotation. 3. Note the machine model, serial number and drive speed. 4. Send everything to Advance Hydraulic Works and ask about availability. 5. Ask the seller to state size, series, condition, source and warranty in writing. 6. Ask for a photo of the actual unit’s nameplate. 7. Compare the delivered pump’s plate with your old one before fitting. 8. Flush the system, fit the pump, prime it and start at low pressure. The usual mistakes are trusting a number without a size, ignoring the series and starting a dry pump. FAQs What is the Sandvik 56024636 45cc piston hydraulic pump? It’s a 45cc piston pump listed under Sandvik reference 56024636, linked by sellers to the LH410 loader. Check your plate for the exact model and series. What is the Sandvik 56024636 45cc piston pump’s sister pump? A listing pairs it with a 28cc A10VO28 under a neighbouring number. They look alike, but their flows differ by about 61%. Is the Sandvik 56024636 hydraulic pump an A10VO45? It may be, since the sister pump is an A10VO28, but the listing doesn’t say. Confirm from the plate. Can Advance Hydraulic Works supply a Sandvik 56024636 hydraulic pump? Send the machine information, component numbers and nameplate pictures to Advance Hydraulic Works and ask approximately availability, source and guarantee before you dedicate. How do I keep away from ordering the incorrect size? Ask the seller to state the displacement and collection, and to show a image of the real plate. Your next step Photograph the nameplate, confirm the size and series, and send everything to Advance Hydraulic Works. You’ll know exactly what you’re buying before you spend anything.
