Excavator Hydraulic Pump
Excavator Hydraulic Pump category is our most comprehensive hydraulic component category, featuring main hydraulic pumps, piston pumps, gear pumps, and fan pumps for all major excavator brands. From Kawasaki K3V series to Hitachi HPV, CAT, Komatsu, and KYB pumps, we supply quality hydraulic pumps for excavators of all sizes.
These pumps are the heart of the excavator hydraulic system, delivering high-pressure oil to cylinders, swing motors, travel motors, and attachments. Each pump is built to OEM specifications for reliable flow and pressure performance. Also see our Excavator Main Control Valve and Hydraulic Fan Motor categories.
Part: 11172358 small bore hydraulic pump, listed at 18 cc by parts suppliers, for the Volvo L60E, L70E, L90E, L110E and L120E wheel loaders and their F and G variants.
Correction: our source record grouped this item with piston pumps for haulers. It is a small loader pump, and the machine list has been corrected here.
Supplied as: new HTD-brand replacement, made in China. MOQ 1 piece, wooden case, dispatch 5 to 8 working days.
Part: 14602252 hydraulic pump for the Volvo EC340D, EC380D and EC480D excavators.
Unresolved conflict in the sources: Chinese dealer listings describe this item as a pilot pump, while our own incoming parts sheet grouped it with the fan drive pumps. We publish it as a general hydraulic pump until a Volvo catalogue entry settles the circuit, and we explain how to confirm it below.
Supplied as: new HTD-brand replacement, made in China. MOQ 1 piece, wooden case, dispatch 5 to 8 working days.
Parts: 840220098, 840220102 and 840220120 gear pumps for Komatsu WB-series backhoe loaders. Komatsu’s own parts catalogue classes 840220120 under the subcategory Gear Pump, which corrects the piston pump label carried in our source data.
Construction: external gear pump, fixed displacement, not a piston pump and not a fan pump.
Supplied as: new HTD-brand replacement, made in China. MOQ 1 piece, wooden case, dispatch 5 to 8 working days.
Part: 708-1W-01840 hydraulic pump for Komatsu PC800-8 class mining excavators, listed in trade parts data under the 708-1W pump group.
Evidence: Komatsu’s online catalogue returns no citable page for this number, so the item name and circuit are trade-established rather than manufacturer-confirmed. We quote against your plate.
Supplied as: new HTD-brand replacement, made in China. MOQ 1 piece, wooden case, dispatch 5 to 8 working days.
Part: 708-1U-00280 pump assembly for the Komatsu GD705-5 wheel scraper. Komatsu’s own parts catalogue returns the item name Pump Assembly for this number, which confirms the type; the circuit is not stated in the data we can check.
Supplied as: new HTD-brand replacement, made in China. MOQ 1 piece, wooden case, dispatch 5 to 8 working days.
Part: 708-1W-00882 main hydraulic pump for the Komatsu WA380-6 and WA430-6 wheel loaders, with 708-1W-41570 listed alongside it for the same application.
Circuit: implement hydraulics. The folder label calling this a fan pump is not supported by any source we could check.
Supplied as: new HTD-brand replacement, made in China. MOQ 1 piece, wooden case, dispatch 5 to 8 working days.
Part: 708-1U-00170 hydraulic steering pump for the Komatsu WA380-6, WA430-6 and WA430-6E0 wheel loaders, with 708-1U-00171 listed as the neighbouring catalogue item for the same application.
Circuit: steering, not cooling fan. Several trade listings call this a fan pump, and that label is not supported.
Supplied as: new HTD-brand replacement, made in China. MOQ 1 piece, wooden case, dispatch 5 to 8 working days.
Parts: 708-1U-00112 and 708-1U-00161 hydraulic pumps for Komatsu WB-series backhoe loaders, published on one page because no source documents a supersession or interchangeability between them.
Circuit: not stated by Komatsu in the data we can check. These are 708-1x pump group items; they are not fan pumps.
Supplied as: new HTD-brand replacement, made in China. MOQ 1 piece, wooden case, dispatch 5 to 8 working days.
Part: 708-1S-00270 main hydraulic pump for the Komatsu PC27MR-2 and PC30MR-2 mini excavators. It is the machine’s implement pump, not a fan pump.
Why this one gets mis-ordered: it carries the 708-1S prefix that also appears on dozer fan pumps, so buyers search it into the wrong category.
Supplied as: new HTD-brand replacement, made in China. MOQ 1 piece, wooden case, dispatch 5 to 8 working days.
Part: 708-1L-00380 main hydraulic pump for the Komatsu D61EX-15, D61EX-15E0 and D61PX-15E0 track-type tractors.
Circuit: implement hydraulics, not the cooling fan. The fan pump on the same machine family is 708-1S-00241, listed separately.
Supplied as: new HTD-brand replacement, made in China. MOQ 1 piece, wooden case, dispatch 5 to 8 working days.
Part: 708-1L-00012 main hydraulic pump for the Komatsu D65EX-12 and D65PX-12 track-type tractors, listed in parts data alongside 708-1L-00011 as the machine’s main pump.
Not a fan pump. The circuit is the implement hydraulic system.
Supplied as: new HTD-brand replacement, made in China. MOQ 1 piece, wooden case, dispatch 5 to 8 working days.
Part: 708-1G-00041 hydraulic steering pump for the Komatsu WA600-6 wheel loader and WD600-6. Dealer parts records list it as a P.O.R. hydraulic steering pump for that machine.
Not a fan pump. Our source folder listed this part under a generic hydraulic pump heading and other listings call it a fan pump; Komatsu’s circuit designation and the dealer records say steering, and that is what we sell it as.
Supplied as: new HTD-brand replacement, made in China. MOQ 1 piece, wooden case, dispatch 5 to 8 working days.
Part: 187-9090 brake supply piston pump for CAT 735, 735B, 740 and 740B articulated dump trucks. Caterpillar lists it as an 18Cc Basic Piston Pump, axial piston variable displacement, and the parts book item name is PUMP GP-PISTON -BRAKE in group 152-6961.
It is not a fan motor or a fan pump. Our incoming parts sheet labelled it that way and the label is wrong; the evidence is set out below. Cat reman equivalent 10R-6685.
Supplied as: new HTD-brand replacement, made in China. MOQ 1 piece, wooden case, dispatch 5 to 8 working days.
Part: 9T-6857 piston pump for CAT 416 and 428 backhoe loaders with the 4.236 and T4.236 diesel engines. Caterpillar lists it simply as PUMP and the parts book item name is PUMP GP-PISTON.
