• Stainless steel, encapsulated motor ensures longevity and impermeability to DEF seepage.
• Heavy-duty shaft provides superior alignment and resistance to stress.
• Double mechanical shaft seals protect the oil-filled bearing chamber from DEF seepage, assuring minimal wear and proper bearing lubrication.
• Stainless steel hydraulics provide superior performance and efficiency.
• Plug-in type EPDM jacket power cable provides ease of service and DEF compatibility.
• Multiple models available to meet global requirements of voltage and frequency.
• All models are suitable for vertical installation where the pump motor is suspended off the bottom of the tank by the discharge piping.

• Materials: Stainless steel construction including impellers/diffusers, inlet/outlet , and outer shell
• Pump type: All models are 5.1″ (130 mm) outside diameter centrifugal type pump
• Power cable: 32.8′ (10 m) EPDM jacketed plug-in power cable
• 60 Hz pump motor: Two-stage pump with 2″ NPT female outlet
• 50 Hz pump motor: Three-stage pump with 2″ BSPT female outlet
• 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˚F, 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.
