KJLC LRV Dual Stage Rotary Vane Pumps

The KJLC LRV Series Dual-Stage Rotary Vane Vacuum Pumps provide reliable pumping performance, effective vapor handling, and long service life for laboratory, industrial, and vacuum process applications. The series offers dependable operation and a competitive cost of ownership.

Each pump includes a proprietary corrosion-resistant internal coating to help protect components from process contaminants and extend service life in demanding environments. The dual-stage rotary vane design delivers deep ultimate vacuum and stable performance across the operating range.

Standard features include a two-position gas ballast valve for handling condensable vapors, an anti-suckback mechanism that helps protect the vacuum system during power loss and forced oil circulation for lubrication and heat dissipation. Heavy-duty construction and precision-machined components also help reduce wear and maintenance needs.

With a practical balance of pumping speed, ultimate pressure, vapor tolerance, and durability, the LRV Series is well suited for research, analytical, coating, semiconductor, and industrial vacuum systems.

Notes:

A single charge of hydrocarbon oil is included with the purchase of a hydrocarbon prepped pump.
PFPE prepped pumps do not include oil; oil must be purchased separately.
Power cord is not included and will need to be purchased separately based on regional plug type.
Pumps that are 3-phase include flying leads attached to the motor. The end user is responsible for wiring the pump.
