Motor driven diaphragm pump offers smooth and quiet chemical dosing. No hard pulses as seen with solenoid driven
pumps.
2,000:1 turndown ratio.
Full stroke every time avoids vapor lock.
Brushless DC motor.
Rated for continuous duty (24/7).
Exclusive DIAFLEX® Diaphragm guaranteed to last the life of the pump.
PVDF / Ceramic pump head components.
Diaphragm Failure Detection (DFD) system. Senses diaphragm failure by detecting chemical in pump head.

service and alarm status in three easy to see colors.
Outputs include: Scalable 4-20mA or pulse, one 250V/6A relay and three 115V/1A contact closures assignable to
monitor various pump functions including DFD, FVS, revolution counter, remote/local, input signals, output signals,
motor on, motor fault, operating mode setting, and others.
CNC precision machined cam and piston for optimum efficiency, unparalleled accuracy, and linearity.
Heavy duty PVDF pump head and valves are standard.
Compatible with Blue-White’s output Flow Verification Sensor (FVS) system.
Includes stainless steel extended mounting brackets. Lifts pump 4-1/2” (11.43 cm), for easy access in hard to reach
areas.
Enclosure Rating:
NEMA 4X:
Constructed for either indoor or outdoor use to provide a degree of protection to personnel against
incidental contact with enclosed equipment; to provide a degree of protection against falling dirt, rain, sleet, snow,
windblown dust, splashing water, and hose-directed water; and that will be undamaged by external formation of ice
on enclosure.
IP66:
No ingress of dust; complete protection against contact. Water projected in powerful jets against enclosure from
any direction shall have no harmful effects.
