API 676 compliant screw pumps

Product catalog summary

Main Characteristics:
PCX and PCXV series pumps are designed for low/medium pressure lubrication circuits and comply with API 676 standards. They feature a steel outer casing, ANSI standard porting, and are available with radial or axial inlets. These pumps are suitable for high viscosity, low noise, and entrapped air applications. They are self-priming, have extremely low pulsation, and can be ATEX certified upon request. Full assemblies with motor, baseplate, and spacer coupling are available.

Installation and Operating Data:
The pumps can be installed indoors or outdoors in industrial or marine environments. They operate within an ambient temperature range of 0 to 60°C, with storage temperatures down to -25°C. They handle hydraulic and lubrication oils with a viscosity range of 10 to 1500 cSt and operate at speeds from 750 to 3600 rpm. The pumps are designed to rotate clockwise, with counter-clockwise rotation available on demand.

Technical Characteristics:
The pumps deliver flow rates from 10 to 5400 LPM and can handle suction pressures up to 10 bar. Delivery pressures reach up to 30 bar for smaller sizes and 20 bar for larger sizes. The operating temperature range is 0 to 70°C, with a maximum of 120°C. The casing is designed for a standard pressure of 16 bar, with hydrotest pressures up to 24 bar. Mechanical seals and radial ball bearings are used, with lubrication provided by the pumped fluid.

Materials and Components:
The casing and flanges are made from carbon or stainless steel, with screws made from nitrided steel. The liner is cast iron or carbon steel, and O-rings are made from Viton®. Surface protection includes sandblasting and an inorganic primer, with finish painting available upon request.

Performance Data:
Performance charts provide detailed information on pressure limits and flow rates for both 50 Hz and 60 Hz operations. The charts indicate the kinematic viscosity for standard ISO VG oils and the required Net Positive Suction Head (NPSH) to prevent cavitation.

Other Products:
The document also lists other products for the oil and gas industry, including the PZ, PX, and MPVA series, each with specific flow rates, pressure limits, and operational characteristics. These products are designed for various applications and can be customized to meet specific requirements.

Company Information:
JBJ Techniques Limited, established in 1974, is committed to providing quality products for mechanical and fluid power applications. The company is ISO certified and offers a range of ATEX certified products. Contact information and additional product offerings are provided.
