Product catalog summary

Main Characteristics:
PCX and PCXV series pumps are engineered for low to medium pressure lubrication circuits, adhering to API 676 standards. They feature a robust steel outer casing, ANSI standard porting, and options for radial or axial inlets. These pumps are ideal for high viscosity, low noise, and entrapped air applications. They are self-priming, exhibit minimal pulsation, and can be ATEX certified upon request. Complete assemblies with motor, baseplate, and spacer coupling are available.

Installation and Operating Data:
The pumps are suitable for both indoor and outdoor installations in industrial or marine settings. They function within an ambient temperature range of 0 to 60°C, with storage temperatures as low as -25°C. They are compatible with hydraulic and lubrication oils, supporting a viscosity range of 10 to 1500 cSt. Operating speeds range from 750 to 3600 rpm, with delivery pressures up to 30 bar for certain models.

Technical Characteristics:
Designed in accordance with the latest API 676 edition, these pumps offer delivery flows from 10 to 5400 LPM. They include a mechanical seal, radial ball bearings, and can be powered by AC or DC electric motors or steam turbines. The casing and flanges are constructed from carbon or stainless steel, with nitrided steel screws and cast iron or carbon steel liners.

Performance Data:
Performance charts are available for both 50 Hz and 60 Hz operations, detailing pressure limits and flow rates for various pump sizes. The charts also provide kinematic viscosity data for standard ISO VG oils and NPSH requirements to prevent cavitation.

Other Products:
The document also references other products in the oil and gas sector, such as PZ and PX series pumps, MPVA series flow meters, and VMPI series pressure relief valves, each with specific delivery flow, pressure, viscosity, and temperature specifications. Custom versions are available for specific applications.
