SERVICE AND REPAIR INSTRUCTION
DISASSEMBLY: Impeller and shaft seal can be inspected and serviced
from lower end of pump by removal of 4 capscrews securing base plate, strainer
screen, and suction cover. Screwdriver slot is provided in end of motor shaft to turn
shaft while holding impeller for removal. This permits removal of impeller without
disassembly of upper motor housing to hold motor shaft. Alternately, there is a shaft
extension with two ats on the rear of the motor for use when the impeller is difcult to
remove. The upper motor cover must be removed to expose this shaft extension.
To service motor remove 4 hex nuts and bump top cover free from housing tube.
Raise sufciently to disconnect power cable connections. Slide housing tube up from
pump casing and motor will be exposed for service or removal.
When servicing the PortaPump and replacing the impeller (part number
444.001.010.) or suction cover (part number 258.001.157.) follow these instructions:The
impeller has been revised to typically require 1 shim (previously 7). The suction cover
has been revised to require 1 gasket (previously 5).
IMPORTANT: Make certain that wire leads are installed per diagram below.
Install top cover as indicated by arrow and instruction on top of cover. Make sure wires
do not contact motor shaft when installing motor cover.
