1. Product Overview

2. Structure & Raw Material

• Pump body: Cast aluminum alloy or nodular cast iron, lightweight and good heat dissipation; heavy-duty models adopt alloy steel forging;

• Gear pair: Alloy steel carburized quenching, high hardness, low abrasion, stable meshing clearance;

• Shaft seal: Oil-resistant NBR/FKM skeleton oil seal, effectively prevent lubricating oil leakage and mud dust intrusion;

• Bearing bush: Bimetallic wear-resistant copper sleeve, reduce rotational friction noise.

3. Working Principle

4. Core Performance Advantages

1. Stable pressure & constant flow

   Little flow fluctuation under variable load, can provide continuous forced lubrication for mud pump crankshaft and crosshead guide.

2. Strong self-priming capacity

   Fast oil absorption without frequent oil filling, adapt to vehicle-mounted and field mobile drilling equipment.

3. Compact small-size structure

   Simple layout, easy to install in narrow power end box space, low overall equipment weight.

4. Wide medium adaptability

   Match gear oil, engine oil, hydraulic lubricating oil; high-temperature resistant customized models for heavy-duty continuous operation.

5. Low failure rate & easy maintenance

   Few vulnerable parts, only shaft seals and gear bushes need regular replacement; split end cover design for quick disassembly and cleaning.

5. Main Application Scenarios

1. Mud pump power end forced lubrication system: Supply oil to crankshaft main bearings, crosshead sliding pairs, transmission gears;

2. Construction machinery: Excavators, loaders, drilling rig gearbox lubrication;

3. Sanitation sprinkler truck, hydraulic station auxiliary oil supply;

4. Generator sets, industrial reducer circulating oil supply.
