This JRRS45BPC28NNNNN3C2NZA2NFFFJJJNNN hydraulic piston pump is an open-circuit variable displacement axial piston pump. It converts rotary mechanical power into hydraulic energy by reciprocating pistons inside cylinder block, and adjusts output flow through swashplate angle change to match varying load demand of hydraulic circuits.
The pump adopts precisely matched piston and cylinder assembly with reinforced cast housing. It maintains stable high pressure output under fluctuating working loads. Optimized internal lubrication reduces friction loss and volumetric leakage for consistent efficiency during continuous heavy-duty operation.
The JRRS45 series includes multiple displacement variants with various control options. It uses standard mounting and port configurations, and can be integrated into open hydraulic circuits for a wide range of mobile heavy machinery.

FEATURES
The swashplate structure enables continuous displacement adjustment, so the pump output flow can be automatically adapted to system load requirements.
Robust pump body structure supports high continuous working pressure, keeping high volumetric efficiency under heavy load working conditions.
Optimized piston distribution design reduces flow pulsation and vibration, realizing smooth and quiet pump operation.
Hardened precision internal components minimize wear rate, extending service life and lowering routine maintenance workload.
Standard flange and oil port layout simplify installation, compatible with many open-circuit hydraulic drive systems of mobile machinery.
APPLICATIONS
Absolutely. We provide OEM/ODM services and can manufacture according to your samples or technical drawings.
For in-stock items, we can ship within 3 days. For custom or non-stock items, delivery usually takes 7–15 days. We’ll confirm exact timing based on current inventory.
Yes, but it’s flexible. Spare parts often have an MOQ of 1 piece, while complete pumps or motors vary by model—please inquire for details.
We are a hybrid—both a manufacturer and a trading company. We produce our own products and also source specific components to offer complete solutions.
We follow strict quality control protocols. All parts undergo CNC machining and heat treatment, and each is 100% tested before delivery to guarantee precision and reliability.
We accept T/T, L/C, Western Union, Alibaba Trade Assurance, and VISA. For new customers, we usually require full prepayment or a 30% deposit with the balance due before shipment.
We offer flexible shipping via express carriers (DHL, FedEx, UPS) and sea freight (CIF/FOB). We can also deliver to your designated freight forwarder in China.
All products come with a 1-year warranty, provided they are installed and operated under normal conditions.
