Motor rating: Continuous operation with motor cooling provided by product flow and protected from dry running
Bypass relief valve with cracking pressure of 30-40 psi (2.1-2.8 bar) and 4 gpm (15 lpm) minimum flow required at the discharge of all models.
Non-return check valve with maximum cracking pressure of 3 psi (0.2 bar) required between product piping and bypass relief valve of all models.
Liquid compatibility: All models are intended for use with Diesel Exhaust Fluid (DEF). DEF is a non-flammable, non-combustible liquid that has a specific gravity of 1.09 at 68¢ªF, and is made per ISO 22241-1 specifications with 32.5% urea and distilled or deionized water. As defined by ISO 22241-1, DEF is the same as AUS 32 (aqueous urea solution).
DEF - PMA YYY Z
DEF = Pump Compatible with DEF
PMA = Pump Motor Assembly
YYY = Pump Motor Hp Rating
150 = 1½ Hp fixed speed (1.1 kW)
Z = Motor Electrical Rating
A = Single phase, 60 Hz, 208-240 VAC (rated 7.9 Amps, requires 25 microfarad run/start capacitor rated 370 VAC)
B = Single phase, 50 Hz, 210-250 VAC (rated 6.9 Amps, requires 30 microfarad run/start capacitor rated 440 VAC)
C = Three phase, 50 Hz, 380-415 VAC (rated 2.6 Amps)
D = Three phase, 60 Hz, 208-240 VAC (rated 5.0 Amps)
Note: Three phase models require overload protection in motor starter. Single phase models have thermal overload protection built into the motor.
