Drilling Equipment Spare Parts (RS11172.16.00A, BQ-C-08, 46513-153, Z07130000019AA)

Core Purpose & Equipment Adaptation

Our full-range drilling equipment spare parts are precision-engineered and supplied to perfectly match a wide range of critical drilling and industrial equipment, including double ram BOP (13-5/8″ 5000PSI), drawworks (JC20, JC750-S, JC70DB, JC40DB), manual choke valves (JLKY-35), BOP control units (FKQ1200-8), drilling rigs (ZJ30), centrifugal pumps (Gorman Rupp T6A3S-B, VS4A60-B), mud and gas separators (NQF-1.2-3.6-0.77), desilters, desanders (DSV-10-3), shale shakers (-HYPERPOOL), and vacuum degassers (VACU-FLO 1200). Key compatible spare parts include RAM variable RS11172.16.00A, brake components (BQ-C-08, BQ-L series) for JC20 drawworks, Gorman Rupp pump parts (46513-153, S1917), hydraulic cylinders (Z07130000019AA, E4022 0000), KEB electromagnetic brakes (05.38.00N-0241), and desilter/desander components (10523-12, 6066-51). We directly address the unique, on-site pain points of three core user segments—drilling operation teams, on-site maintenance technicians, and procurement professionals—each relying on our parts to keep drilling equipment running safely, continuously, and without costly interruptions. Drilling operation teams face catastrophic risks from component failures: a faulty BOP ram, brake block, pump seal, or hydraulic cylinder can halt drilling operations entirely, damage expensive equipment, cause mud/gas leaks, and expose workers to life-threatening safety hazards (e.g., well control incidents, drawworks malfunctions). Maintenance technicians need easy-to-install, OEM-compatible parts with clear, practical guidance to resolve mechanical, hydraulic, and structural faults quickly—without specialized training across dozens of component types and equipment models—saving critical time and reducing labor costs. Procurement professionals struggle with sourcing full-range, equipment-specific parts (for JC20/JC750-S drawworks, ZJ30 rigs, Gorman Rupp pumps) that meet strict drilling industry standards (API Spec 16A for BOPs, API Spec 7K for drawworks, ISO 9001 for quality), avoid ill-fitting components that cause repeated breakdowns, and align with tight budgets while ensuring compliance with safety regulations. The core purpose of our products is to eliminate these pain points by providing direct-fit, high-quality replacements for all mission-critical drilling components—covering BOP parts, brake components, hydraulic cylinders, pump parts, valves, electromagnetic brakes, separators, and solids control equipment parts—all designed to withstand the harsh, high-pressure, high-vibration, and corrosive conditions of onshore/offshore drilling, reduce operational downtime, and ensure continuous, compliant rig operation.

On-Site Fault Maintenance Cases

Below are 3 real, short on-site drilling fault cases—reflecting common issues faced by drilling teams—demonstrating how our direct-fit spare parts resolve critical problems quickly, minimize downtime, and restore operational efficiency:

Case 1: JC20 Drawworks Brake Failure Due to Worn BQ-C-08 Brake Blocks

A drilling rig experienced a critical brake failure on its JC20 drawworks due to worn BQ-C-08 brake blocks. The brake blocks had degraded beyond safe limits, preventing the drawworks from stopping reliably during hoisting operations—posing a severe safety risk to workers and equipment.Solution: Replaced the worn BQ-C-08 brake blocks with our OEM-compatible parts, adjusted the brake clearance, and tested the braking system under load. The drawworks resumed full, safe operation within 1 hour, eliminating the safety hazard and minimizing downtime.

Case 2: Gorman Rupp T6A3S-B Pump Leakage from Faulty 46513-153 Mechanical Seal

A drilling operation’s Gorman Rupp T6A3S-B centrifugal pump experienced severe fluid leakage due to a faulty 46513-153 mechanical seal. The leaking seal caused reduced pump efficiency, wasted drilling fluid, and threatened to damage the pump’s internal components.Solution: Replaced the faulty 46513-153 mechanical seal with our direct-fit part, flushed the pump system, and tested for leaks. The pump resumed full, leak-free operation within 45 minutes, restoring fluid circulation and drilling efficiency.

Case 3: ZJ30 Rig Hydraulic Cylinder Malfunction (Z07130000019AA)

A ZJ30 drilling rig’s telescopic cylinder assembly (Z07130000019AA) failed to extend properly due to a damaged seal, halting mast raising operations. The faulty cylinder prevented the rig from being prepared for drilling, causing costly downtime. Solution: Replaced the damaged Z07130000019AA telescopic cylinder assembly with our OEM-compatible part, bleed the hydraulic system, and tested the cylinder movement. The rig’s hydraulic system resumed normal operation within 2 hours, allowing mast raising to be completed and drilling to resume on schedule.
