Part of the Cavitation Line, CRL high-speed sliding vane pumps are durable motor-speed pumps offer capacities from 5 to 22 U.S. gpm (19-83 L/min), and are ideal for loop systems and low volume transfer applications. CRL models are designed for foot-mounting to a common baseplate.
Available with 1.25- or 1.5-in NPT tapped ports, all models are equipped with an internal relief valve, and a replaceable casing liner and end discs for easy rebuilding of the pumping chamber if ever necessary. The CRLR 1.25-in model features a special liner which offers lower flow rates than the CRL 1.25-in pump.
Standard construction materials for these pumps include silicon carbide mechanical seals and laminate vanes. Maximum differential pressure for the CRLR 1.25 is 70 psi (4.83 bar), and 100 psi (6.89 bar) for the CRL 1.25- and CRL 1.5-in models.
Assembled pump units are available from the factory, with or without motors. For dimensions of assembled pump units, refer to catalog dimension sheets.
Features and Benefits
Cavitation suppression liner design for reducing the noise, vibration, and wear normally caused by entrained vapors
Replaceable casing, liners and end discs allow easy rebuilding of the pumping chamber to like-new condition
Ductile-iron construction with internal relief valve
Blackmer mechanical seal and ball bearing construction provide maximum reliability
Symmetrical bearing support assures even loading and wear for long life
Adjustable relief valve protects pump against excessive pressures
External ball bearings are isolated from pumpage by mechanical seals to maximize bearing life and minimize contamination risk
Advantages of sliding vane technology:
Unique sliding-vane pump design self-adjusts for wear to maintain flow rates
Excellent self-priming and dry-run capabilities
Sliding vane design provides sustained performance and trouble-free operation
Easy maintenance: vanes can be easily replaced without removing the pump from the piping system
