- Low pump rpm means long service life
- Wide range of pumping speeds, 0.9 to 23 cfm
- Rugged design for tough applications
- Proven dependability
- Low ultimate pressures to 1 x 10-4
- Elliptical bore design produces high free air displacement with low rpm
Because Duoseal pumps operate at a low rpm, they run cooler and reach a lower ultimate pressure with less back-streaming than higher rpm models. Another proven advantage of low speed is a reduced rate of friction and wear on pump components which has resulted in a longer service life for Duoseal pumps. Warranty: 1 year.
*All single phase, dual voltage, thermal load-protected motors come wired for low voltage setting. Explosion-proof motors are rated Class I, GrD; Class II, GrE, F, G.
