Applications

Shallow well, Deep well and Convertible pump appli-
cations. Grundfos jet pumps are self-priming centrifu-
gal pumps suitable for domestic water supply systems,
light agricultural and industrial water transfer applica-
tions

Pumps

JPF2A, JPF3A, JPF4A, JPF41A Pumps:

Rugged cast iron construction. Single-stage shallow
well self-priming centrifugal pumps. End suction, top
discharge arrangement and Technopolymer impeller.
Pump has built-in ejector complete with clean out port
to clear blockages from nozzle. Convenient priming
plug for ease of priming and air elimination. Ceramic-
Carbon bellows mechanical seal ensures trouble-free
operation.

JPF5A & JPF7A Pumps:

Rugged cast iron construction. Multistage convertible
self-priming centrifugal pumps. End suction, top dis-
charge arrangement with detachable ejector assembly
for deep well applications and Technopolymer impel-
lers. Convenient priming plug for ease of priming and
air elimination. Ceramic-Carbon bellows mechanical
seal ensures trouble-free operation.

JDF2A & JDF4A Pumps:

Rugged cast iron construction. Single-stage deep
well self-priming centrifugal pumps. End suction, top
discharge arrangement and Technopolymer impel-
ler. Pump has separate deep well port for connection
to Deep Well ejector kit. Convenient priming plug for
ease of priming and air elimination. Ceramic-Carbon
bellows mechanical seal ensures trouble-free opera-
tion.

JPS2A & JPS4A Pumps:

Corrosion resistant stainless steel construction.
Single stage shallow well self-priming centrifugal
pumps. End suction, top discharge arrangement and
Technopolymer impeller. Ceramic-Carbon bellows
mechanical seal ensures trouble-free operation.

Motors

All jet pump motors are totally enclosed and fan-
cooled design for quiet operation and superior protec-
tion in harsh environments. Stainless steel motor shaft
offers excellent corrosion resistance. Double, oversized
greased ball bearings are maintenance-free sealed for
life. All motors have built-in thermal overload protec-
tion and are capacitor-run, with no switches to fail.
Drive end motor bearing protected by durable lip seal.

Insulation class F, motor protection IP44, terminal box
protection IP55.

Pumped Liquid

Only use on clean, non-viscous, non-aggressive, non-
explosive liquids. Pump not to be used on pool water
applications or hydrocarbon transfer (i.e. diesel, gaso-
line, etc).

Agency Approvals:

CSA -Std C22.2 No 108, No 77-95.

Mounting Position:

Shaft in horizontal position only for all pumps.
