General data
Applications
Shallow well, Deep well and Convertible pump
applications. Grundfos jet pumps are self-priming
centrifugal pumps suitable for domestic water supply
systems, light agricultural and industrial water
transfer applications
Pumps
JPF2A, JPF3A, JPF4A, JPF41A Pumps:
Rugged cast iron construction, single-stage shallow
well 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
centrifugal pumps. End suction, top discharge
arrangement with detachable ejector assembly for
deep well applications and Technopolymer impellers.
Pump 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.
JDF2A & JDF4A Pumps:
Rugged cast iron construction, single-stage deep
well centrifugal pumps. End suction, top discharge
arrangement and Technopolymer impeller. 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 operation.
JPS2A & JPS4A Pumps:
Corrosion resistant stainless steel construction, single
stage shallow well 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.
Motor insulation class F. NEMA 3R enclosure rating on
motor terminal box.
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.
