Our spare parts solve the practical problems of difficult procurement of special models, poor compatibility of non-original parts, short service life, and high maintenance frequency, providing a reliable guarantee for the stable operation of pump equipment in various harsh and complex environments.

Function Description

Each spare part is designed to target specific pump functions and solve practical application pain points: Pump head X01177001 SB68FJ-4.1.0 is tailored for SB series low-lift air conditioning and refrigeration pumps, with stable flow output and strong compatibility, solving the problem of flow instability and pump head cracking in air conditioning spray and cold water circulation scenarios; Pump head X11175001 SB68FJ-6.1.0A is designed for high-pressure working conditions, withstanding a maximum working pressure of 1.8MPa, avoiding leakage and damage caused by high pressure in oilfield water injection and fire-fighting water supply; Impeller SB23J-50.1.2 is made of high-wear-resistant stainless steel, with a streamlined design to eliminate backflow and blockage, solving the problem of reduced water output and increased energy consumption caused by wear and sand accumulation; Mechanical seal assembly VJ34-L adopts a double-seal structure, achieving zero leakage and reducing environmental pollution and maintenance frequency, which meets the strict sealing requirements of industrial refrigeration and chemical fluid transportation; Bearing 6314E GB/T276-1994 has high load-bearing capacity, with a rated dynamic load of 113kN, solving the problem of bearing damage and pump jamming caused by heavy load; Oil seal 40×62×8 W12124402 effectively prevents lubricating oil leakage, extending the service life of bearings and reducing maintenance costs.

Structural Features

Our pump spare parts have obvious structural advantages to adapt to diverse working environments such as oilfields, industrial workshops, and high-rise buildings: all pump heads (including SB68FJ-4.1.0, SB68FJ-6.1.0A) adopt an integrated casting structure, no welding seams, improving structural strength and avoiding breakage during long-term operation—especially suitable for the frequent start-stop working condition of air conditioning and refrigeration pumps; impellers are made of high-wear-resistant stainless steel, with a wear resistance of 1400 hours in high-sand oilfield environments, which is 450 hours longer than ordinary impellers; fasteners such as Bolt M20×90 GB/T5781-2000 and Nut M16 W03012016 adopt hot-dip galvanizing treatment, resisting corrosion in humid and corrosive environments for up to 1700 hours; mechanical seal assemblies use corrosion-resistant fluorine rubber materials, with a sealing life of up to 1000 working hours; bearings 6314E GB/T276-1994 are equipped with dust-proof covers, preventing dust and debris from entering and extending service life by 300 working hours; bases (such as SB34-35.5.0) are made of high-strength cast iron, with strong load-bearing capacity and good shock absorption, reducing pump vibration and noise in high-rise building equipment rooms. All structural designs are optimized for SB series pumps, ensuring perfect matching and stable operation.

Applicable Working Conditions

Our pump spare parts are widely applicable to various working scenarios, focusing on oilfield exploitation, industrial refrigeration, high-rise building water supply, and fire-fighting systems—consistent with the application scope of SB series pumps. In onshore and offshore oilfields, our products (such as SB68FJ-6.1.0A pump head, SB23J-50.1.2 impeller) can adapt to a temperature range of -30℃ to 100℃ and a maximum working pressure of 2.0MPa, solving the problem of spare parts damage caused by extreme temperature, high pressure and high sand content; in industrial refrigeration systems and air conditioning rooms, our spare parts (such as SB68FJ-4.1.0 pump head, Mechanical seal assembly VJ34-L) can adapt to low-temperature working conditions (-10℃ to 60℃), ensuring stable operation of cold water circulation pumps; in high-rise buildings and fire-fighting systems, our high-pressure pump heads and load-bearing bearings ensure stable water supply and fire-fighting efficiency. All products are compatible with SB series pumps (SB68, SB56, SB45, SB23), centrifugal pumps, and refrigeration water pumps, and can be directly replaced without modifying the equipment structure, meeting the diverse needs of different industries.

Maintenance and Maintenance Suggestions

To extend the service life of pump spare parts and ensure the stable operation of pumps, especially SB series pumps used in diverse scenarios, our professional engineers with more than 13 years of on-site maintenance experience provide the following practical maintenance suggestions (with operation tips to avoid pitfalls):

• Pump Heads (SB68FJ-4.1.0, SB68FJ-6.1.0A): For air conditioning and refrigeration pumps, check the sealing surface every 100 working hours to avoid leakage caused by debris accumulation; for oilfield high-pressure pumps, replace the sealing gasket every 280 working hours, and do not use expired gaskets (expired gaskets will lose elasticity and cause leakage); clean the pump head surface every 150 working hours in corrosive environments.

• Impellers (SB23J-50.1.2, SB34J-40.1.1): Clean the impeller surface every 70 working hours to remove sand and attachments, avoiding unbalanced rotation caused by uneven weight; check the impeller wear every 400 working hours, and replace it when the wear exceeds 0.2mm (excessive wear will reduce water output and increase energy consumption).

• Bearings and Seals: Check the bearing temperature every 80 working hours, and stop the machine for inspection if it exceeds 80℃ to avoid bearing damage; add lubricating oil every 120 working hours, and use the specified model of lubricating oil (do not mix different types of lubricating oil); replace mechanical seals every 950 working hours to avoid leakage, and check O-rings for aging every 300 working hours.

• Fasteners: Check the tightness of bolts and nuts every 60 working hours, and fasten them in time (do not over-tighten, which will damage the thread); for GB/T standard fasteners (such as Bolt M20×90 GB/T5781-2000, Spring washer 16 GB/T93-1987), do not replace them with non-standard products, as this will affect the stability of the pump structure.

• Pulleys and V-belts: Check the V-belt tightness every 50 working hours, and adjust it in time to avoid slipping; replace V-belts every 2100 working hours, even if there is no obvious wear, to prevent sudden breakage during operation; clean the pulley surface every 100 working hours to remove dust and debris.

• Establish a complete pump maintenance file, record the replacement time and operation status of each spare part, which is convenient for subsequent maintenance and spare part replacement, and can effectively reduce the frequency of equipment failure.
