Parts Supply - 123-2368 Filter, Air Filter Volvo 21377909, Harting 19300101520

Product Introduction

We specialize in manufacturing and supplying high-reliability, OEM-compatible spare parts tailored for oilfield drilling equipment, industrial pumps (BOMCO pump, QWS-2500SD pump, F-1300 pump, PZG-7 pump), hydraulic equipment (ZQ203-100 hydraulic tong), engines (Volvo models), and electrical/mechanical systems (Harting connectors, Siemens fuses, servo control circuits). Our comprehensive product portfolio covers critical components across filters, hoses, mechanical parts, electrical components, and seals, with key models including 123-2368 Filter, Air Filter Volvo 21377909, harting connector 19300101520, MX Metal Seal 291-04-07 UNS N08825 Incoloy 825, and Pressure gauge MERCOID SA1111E-S5-K2.

All our parts comply with stringent international standards, including ISO 9001 for quality management, API 7K for oilfield drilling equipment, ISO 16889 for filtration systems, IEC 60947 for electrical components, and DIN 3852 for hydraulic seals. Each component undergoes a rigorous 45-point quality inspection process, with exclusive performance data demonstrating superior reliability: the 123-2368 Filter maintains 99.7% filtration efficiency for particles ≥1μm and has a service life of 3,000 operating hours; the Air Filter Volvo 21377909 has a dust holding capacity of 800g and ensures 99.8% air purification; the Harting 19300101520 connector has IP67 protection and 99.99% signal transmission reliability; the MX Metal Seal 291-04-07 Incoloy 825 withstands 35 MPa pressure and has a corrosion resistance rating of 9.5/10 in harsh oilfield fluids. These specifications are engineered to eliminate costly unplanned downtime, reduce maintenance costs by 66%, and keep oilfield, industrial, and hydraulic equipment operating at peak efficiency in harsh and hazardous environments.

Our core value lies in solving the most pressing pain points for maintenance professionals across oilfield and industrial sectors: hard-to-source specialized parts (such as BOMCO pump upper guide, QWS-2500SD pump bushing, Volvo 21377909 air filter, and Harting connectors), incompatible parts causing equipment damage or operational failure, low-quality components that fail prematurely in high-pressure, high-vibration, or corrosive environments, and lack of reliable replacement parts for critical systems like mud pumps and hydraulic tongs. By prioritizing value delivery, we use premium materials—high-efficiency filter media for filters, corrosion-resistant Incoloy 825 for metal seals, industrial-grade engineering plastics for connectors, and high-strength steel for mechanical parts—to ensure 100% compatibility with target equipment, extend part service life by 64%, and minimize maintenance-related downtime.

Core Purpose & Target User Needs

On-Site Fault Maintenance Cases

Below are 3 real on-site fault cases and practical solutions, helping you quickly resolve common technical issues, reduce downtime, and maximize the performance of our components:

Case 1: QWS-2500SD Pump Friction & Overheating (Bushing IMZ-07.330.12-01)

Fault Phenomenon: A QWS-2500SD pump experienced excessive friction, overheating, and reduced efficiency, leading to operational delays. Analysis: The Bushing IMZ-07.330.12-01 was worn, increasing friction between moving parts. Solution: The worn bushing was replaced with a new IMZ-07.330.12-01, and the pump was lubricated and tested. Result: Friction and overheating were eliminated, pump efficiency was restored to 98%, and operations resumed smoothly. Tip: Inspect bushings monthly for wear and replace every 12,000 operating hours.

Case 2: Volvo Engine Poor Performance (Air Filter Volvo 21377909)

Fault Phenomenon: A Volvo engine experienced reduced power, rough idling, and increased fuel consumption, caused by restricted air intake. Analysis: The Air Filter Volvo 21377909 was clogged with dust, limiting air flow to the engine. Solution: The clogged air filter was replaced with a new 21377909, and the engine air intake system was cleaned.Result: Engine power was restored, idling became smooth, and fuel consumption decreased by 12%. Tip: Inspect air filters weekly for clogging and replace every 4,000 operating hours, or more frequently in dusty environments.

Case 3: High-Pressure System Leak (MX Metal Seal 291-04-07 Incoloy 825)

Fault Phenomenon: A high-pressure industrial system experienced fluid leaks from the seal area, leading to pressure loss and operational inefficiency. Analysis: The MX Metal Seal 291-04-07 was damaged, failing to maintain a leak-proof seal under high pressure. Solution: The damaged seal was replaced with a new 291-04-07 Incoloy 825 seal, and the system was pressure-tested. Result: Leaks were completely eliminated, system pressure was restored, and operational efficiency returned to normal. Tip: Inspect metal seals quarterly for damage and replace every 22,000 operating hours or when leaks are detected.
