ZQJ125*8-X Desilter Cyclone, Wavy Screen Cloth 140/20 Mesh*1050*695 & SB68J Sand Pump Parts

Introduction

In oilfield drilling solids control systems, downtime from worn screens, leaking seals, damaged cyclones, or failed pumps directly impacts operational efficiency and cost. Our comprehensive spare parts lineup—including ZQJ125*8-X desilter cyclone, wavy screen cloth 140/20 mesh1050695, SB68J sand pump bearing, GX-1/700*1050/40 mesh plane screen, and FLC530 tension jaw 14612-01—is fully compatible with Derek, SWACO, REEICK, and common sand pumps (SB6-8-55kW, LTSB6-8 75KW), vibrating screens (2YZS, XQJS-300*2WG), and degassers (RCQ240, ZCQ320).

Our core value lies in solving critical pain points: screen blinding/breakage reducing separation efficiency; mechanical seal leakage causing fluid loss and contamination; cyclone wear leading to under-separation; pump bearing overheating and jamming; and screen frame misalignment from faulty tensioning jaws. We deliver 100% interchangeable, durable parts that extend service life, reduce unplanned downtime, and ensure consistent performance in high-sand, high-temperature, and corrosive oilfield environments—all meeting API RP 13C (screens), API 610 (pumps), and ISO 9001:2015 standards[4]. Backed by 22 years of manufacturing experience, our parts have a field failure rate of 0.29 per 1,000 units, far below the industry average of 1.08 per 1,000 units, and are supplied to 35+ countries.

Function & Structural Features

Vibrating Screen Components

• Wavy Screen Cloth 140/20 Mesh1050695: Features a dual-mesh structure (140 mesh for fine particles, 20 mesh for coarse material) and wave-shaped weave that increases effective area by 125–150% compared to flat screens. Constructed from 316L stainless steel with anti-blinding and anti-wear treatments, it handles flow rates of 200 m³/h and separates particles as small as 74 μm (API 140), solving screen blinding and breakage in high-sand drilling fluids.

• GX-1/700*1050/40 Mesh Plane Screen: Engineered for high-capacity coarse screening, with a rigid frame and high-opening-area weave (37% open area). Its 40 mesh specification (385 μm aperture) efficiently removes large particles, reducing wear on downstream equipment.

• SWACO BEM3 Shock Absorber RS3K80340: Made of high-elasticity rubber with a Shore A hardness of 65, it absorbs vibration impact up to 8 g-force, reducing screen frame wear and noise. It extends vibration motor life by 3–5 years compared to standard absorbers.

• FLC530 Tension Jaw 14612-01: Precision-machined from high-strength alloy steel with a wear-resistant coating, it ensures secure screen frame clamping, preventing misalignment and screen displacement during high-vibration operations.

Pump Parts

• SB68J Sand Pump Bearing: Manufactured from high-carbon chromium steel with a hardness of HRC 62–65, it has a dynamic load capacity of 78 N/mm² and a service life of 11,500 operating hours. It solves bearing overheating and jamming in high-load sand pumps (SB6-8-55kW, LTSB6-8 75KW) operating at temperatures up to 90°C.

• WJQ5*6J-10 Mechanical Seal: Features silicon carbide sealing faces and a metal bellows structure, with a leakage rate of less than 0.08 ml/min. It prevents fluid leakage and contamination in sand removal and liquid supply pumps (LW450-842 ZW-30-21-5.5kW), even in abrasive slurries.

• 4PWL Sand Pump Oil Mirror SB-200: Constructed from tempered glass with a stainless steel frame, it allows real-time monitoring of lubricant levels in pump bearings, preventing dry-run damage and extending component life.

Cyclone Components

• ZQJ125*8-X Desilter Cyclone: Designed for fine particle removal (20–74 μm), with a 125mm diameter and dual-cone structure. It handles flow rates of 180 m³/h and uses a replaceable polyurethane liner to resist wear, reducing maintenance frequency by 60% compared to metal liners.

• 2/48-120F-4TA Desilter Cyclone Funnel: Machined from wear-resistant cast polyurethane, it ensures smooth fluid flow into the cyclone, minimizing pressure loss and preventing clogging. Its smooth inner surface reduces fluid turbulence by 22%, improving separation efficiency.

Maintenance & Operation Tips

Our senior oilfield engineers provide practical, field-tested tips to extend part life and avoid common failures:

1. Vibrating Screens: Inspect wavy/flat screens every 12 days for wear or blinding; clean with low-pressure water (0.4–0.6 MPa) to avoid mesh damage. Replace shock absorbers (RS3K80340) if compression exceeds 15% of original size. Tighten tension jaws (14612-01) every 7 days to prevent screen displacement.

2. Pumps: Check SB68J bearings every 30 days for lubrication; use lithium-based grease (fill 65% of bearing cavity) to prevent overheating. Replace WJQ5*6J-10 mechanical seals if leakage exceeds 0.5 ml/h—avoid mixing seal models, as this causes immediate leakage. Monitor oil mirror (SB-200) levels daily to prevent dry runs.

3. Cyclones: Inspect ZQJ125*8-X cyclones monthly for wear (depth ≥1 mm = replace); clean funnels and elbows weekly to prevent clogging. Tighten cyclone clamps (50-15-052) every 7 days to avoid joint leakage.

4. General: Store parts in a dry, dust-free warehouse (temperature 5–28°C) to prevent material aging. Never mix adjusting bolts or springs—using the wrong part will damage equipment. Operate valves (DN80) smoothly to avoid water hammer; exercise them monthly to prevent seat sticking.
