The Bimetal Hydraulic Pump Wear Resistant Plate is designed for hydraulic pumps that operate continuously in environments where oil cleanliness may be difficult to maintain.

It is suitable for equipment exposed to dust, minor oil contamination, and long working cycles.

Material Structure

The product uses a high-strength cold-rolled steel backing combined with a copper alloy friction layer.

A solid lubricant phase is evenly distributed throughout the copper alloy layer.

Boundary Lubrication Protection

The solid lubricant phase continues to reduce friction when the oil supply is temporarily insufficient.

This helps lower the risk of surface burning caused by short periods of boundary lubrication or dry contact.

Wear Resistance

Under oil lubrication, the wear rate is controlled within 0.01 mm per 1,000 hours.

According to the supplied product data, its service life is more than 50% longer than that of a conventional bimetal side plate under comparable operating conditions.

Oil Cleanliness Adaptability

The product is suitable for hydraulic oil with a cleanliness level of NAS 8–10.

It can tolerate light oil contamination while maintaining stable wear performance.

Operating Conditions

The rated working pressure is up to 25 MPa. The copper alloy layer has a hardness of HB 80–110.

These properties support continuous operation in demanding industrial environments.

Application Areas

This Bimetal Hydraulic Pump Wear Resistant Plate is suitable for hydraulic pumps used in metallurgy, mining, building material production, construction machinery, and port machinery.

It is especially useful for equipment that must operate for extended periods without frequent shutdowns.

Customization Support

Production is available according to customer drawings or physical samples. The minimum order quantity is 100 pieces.

Custom samples normally require 30 days. Urgent samples may be completed about five days earlier.

Delivery and Warranty

Standard delivery is 25–30 days. Repeat orders may be delivered approximately one week earlier.

A six-month warranty is provided. Returns or replacements are handled within five days.

Production and Inspection

The factory has three continuous bimetal sintering lines and 30 machining centers, including 12 imported machines.

Export products receive a 100% inspection before packing.

Export Packaging

Small orders are packed in wooden cases with metal fasteners. Orders above half a ton are placed on iron pallets and secured with stretch film.
