Pumps General Characteristics

Miniature, brushless DC, diaphragm pumps.
True brushless DC motor, not an inverter-driven AC motor.
Motor and crank pin bearings are double-shielded, instrument type ball bearings lubricated for the life of the unit.
Pumping section(s) consist of synthetic rubber diaphragms housed in molded plastic or aluminum casings directly driven from the motor shaft by a scotch yoke-crank assembly.
Valves are self-biasing, fiberglass reinforced synthetic rubber or other elastomer.
No metallic springs are used.
Air or gas being pumped contact only the plastic and synthetic rubber areas.
All moving parts are completely enclosed.
Small physical size and extremely low power drain-to-air delivery ratio; ideal for portable applications where only battery power is available.
Motor generates no radio frequency interference (RFI) and all electronic components are contained within the motor housing.
Pumps may be mounted in any position.

Life expectancy is 10,000 hours or more (except diaphragms - see below), continuous duty.

Diaphragm life expectancy exceeds 5,000 hours for standard Neoprene. Viton diaphragms can exceed 12,000 hours. Actual diaphragm life is dependant upon service conditions.
Diaphragms are field replaceable
