Product Introduction
This curated selection covers all high-wear critical components for Zhejiang Keer DY155-67 and DY180-67X10 pumps, including flexible laminated membrane coupling parts, wear rings, bushings, impellers, shafts, bearing assemblies, O-rings, gaskets, fasteners, and sealing accessories. Every part is manufactured to meetGB/T standard specifications, ISO 9001 quality benchmarks, and hydraulic pump performance requirements, with strict dimensional inspection and material testing to withstand continuous pumping stress. The assortment includes both standard fasteners (per GB1235-76, GB1096-79) and custom hydraulic components, fully traceable to original Keer Pump part numbers for simplified inventory and emergency repairs.
Functional Performance Specifications
These Keer pump spares deliver consistent hydraulic and mechanical performance: wear rings and bushings maintain tight radial clearances to preserve pump efficiency and reduce internal recirculation; precision-machined impellers restore rated flow rates and pressure output; high-quality elastomer O-rings and gaskets provide leak-free sealing under pressure and temperature cycling; SKF thrust bearings (7309B/DB) ensure stable shaft rotation with a rated service life of up to 50,000 operating hours; and flexible laminated membrane coupling components absorb vibration and misalignment to protect drive train integrity. All parts are engineered to maintain pump performance within ±2% of OEM rated output.
Structural & Material Features
- OEM-Certified Dimensional Accuracy: Machined to ±0.003 inch tolerance for perfect drop-in fitment, eliminating alignment issues and installation delays
- Wear-Resistant Materials: High-grade cast iron for impellers and casings, hardened alloy steel for shafts and bearings, and oil-resistant nitrile rubber for seals/O-rings
- Precision Balance Treatment: Rotating components (impellers, balancing drums) undergo dynamic balancing to G2.5 grade, minimizing vibration and extending bearing life
- Modular Repair Design: Pre-sized seal kits, bearing sleeves, and wear parts reduce field repair time by up to 60% compared to custom fabricated components
- Compliant Standard Fasteners: All keys, locknuts, and O-rings conform to Chinese national standards (GB series), ensuring universal compatibility and quality consistency
Applicable Operating Conditions
These spare parts are built for heavy-duty industrial and petroleum pumping environments, optimized for multistage centrifugal pump applications in drilling fluid transfer, water circulation, industrial process pumping, and wastewater management. They perform reliably in ambient temperatures ranging from -10°F to 180°F, handling clean water, abrasive drilling mud, and mild chemical fluids, with resistance to corrosion, erosion, and continuous high-speed rotation. Components are rated for both intermittent and 24/7 continuous pump operation.
Maintenance & Service Recommendations
- Inspect wear rings, bushings, and sealing components every 2,000 operating hours for signs of wear, scoring, or degradation to prevent efficiency loss
- Lubricate thrust bearings and bearing sleeves quarterly with recommended pump oil to prevent dry friction and premature failure
- Replace O-rings, gaskets, and packing during every pump disassembly to maintain leak-free sealing and pressure integrity
- Check shaft alignment and coupling condition every 6 months to reduce vibration and extend drive train component life
- Stock critical wear parts (impellers, wear rings, bearings, seals) preventatively to minimize unplanned downtime during pump repairs

Field Failure Repair Case Studies
Case 1: DY155-67 Pump Wear Ring Degradation
A Keer DY155-67 pump experienced significant pressure loss and reduced flow due to worn casing wear rings (DY155-67-0015). Installing OEM replacement wear rings restored hydraulic efficiency, bringing pump output back to full rated pressure and eliminating internal fluid recirculation.
Case 2: DY180-67X10 Thrust Bearing Failure
Excessive vibration and shaft noise occurred in a DY180-67X10 pump due to a failed SKF 7309B/DB thrust bearing. Replacing the faulty bearing with an authentic OEM unit eliminated vibration, stabilized shaft rotation, and prevented further damage to rotating components.
Case 3: Seal Leakage in Coupling Assembly
A flexible laminated membrane coupling on a DY155-67 pump developed lubricant leakage due to a damaged pack disk (TDG6-520-10). Swapping the worn disk with a genuine Keer replacement restored sealing, preventing lubricant loss and maintaining coupling performance.
