This AT223519 series hydraulic piston pump is a variable displacement axial piston pump. It converts mechanical rotational power into hydraulic energy by reciprocating pistons inside cylinder block, and adjusts output flow by changing the swashplate angle to match different load demands of hydraulic circuits.
The pump adopts precision piston and cylinder assembly with reinforced cast iron housing. It delivers stable high-pressure output under fluctuating loads, with optimized internal lubrication design to reduce friction loss and maintain consistent efficiency during continuous heavy-duty operation.
The AT series contains multiple model variants with different displacement options. It supports various control modes and uses standard connection interfaces, which can be matched with open or closed hydraulic circuits for a wide range of mobile heavy machinery.

FEATURES
It changes pump displacement by adjusting swashplate angle, so the output flow can be adjusted dynamically according to system load requirements.
Reinforced pump body structure supports high working pressure, maintaining high volumetric efficiency under heavy load working conditions.
Optimized piston distribution structure reduces flow pulsation, ensuring smooth pump operation and lowering system vibration.
Hardened precision internal components minimize wear, extending service life and decreasing frequency of routine maintenance.
Standard mounting and port layout allow easy installation, compatible with open and closed hydraulic circuits for many heavy machinery types.
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.
