- Carbonator-Mount Rotary Vane Pumps
- Couplings absorb most of the wear usually inflicted upon pump and motor shafts to protect both in the event of misalignment, extending pump/motor life. Can be easily and inexpensively replaced as needed. Use only with slotted rotors.
- These positive displacement pumps run quietly, have low vibration and pulsation characteristics, and are virtually maintenance-free. They can handle many liquids with low lubricating characteristics at relatively high pressures. Flow remains constant over entire pressure range. Most models are self-priming (except 6XE92 and 6XE95). Metal-to-metal contact is eliminated, resulting in low starting torque. 303 stainless steel shaft, stainless steel rotors, and built-in relief valve. Pumps mount on NEMA 56C frame motors (adapter kit sold separately) for a coupling drive, or can be attached to a NEMA 48YZ motor with a V-band clamp. High-temperature plastic internal bypass valve eliminates the need for an external relief valve on all models except 6XE92 and 6XE95. (6XE82 and 6XE84 have internal solid-brass bypass valves. Brass and stainless steel also available on all other models; call your local branch.) Pumps work with carbonated, deionized, or distilled water and moderately aggressive liquids such as fire-resistant fluids, hydraulic oil, lubricants, coolants, insecticides, and soap in dispensers, espresso machines, sprayers, filtration and water purification processes, team-cleaning and car-washing machines, pressure boosters, atomizing/misting humidification systems, circulation systems, laboratory pumps, pilot plants, boiler feeds, textile machines, and fire jockey pumps.
- Max. fluid temp.: 150 F Max. operating pressure: 200 psi Relief valves preset to 250 psi NSF rated, except 6XE82 and 6EX84
