Back Cover Installation
(Figure 10, Page 21)
If the wear plate (16) was removed for replacement, carefully centre it on the back
cover and secure it with the hardware (19 and 20). The wear plate must be concentric
to prevent binding when the back cover is installed.
Replace the back cover O-ring (18), and lubricate it with a generous amount of No.2
grease. Clean any scale or debris from the contacting surfaces in the pump casing that
might interfere or prevent a good seal with the back cover. Slide the back cover
assembly into the pump casing. Be sure the wear plate does not bind against the
impeller.
NOTE:
To ease future disassembly, apply a film of grease or ‘Anti-Seize’ on the
back cover shoulder, or any surface which contacts the pump casing. This
action will reduce rust and scale build-up.
Secure the back cover assembly by tightening the hand nuts (21) evenly. Do not over-
tighten the hand nuts; they should be just tight enough to ensure a good seal at the
back cover shoulder. Be sure the wear plate does not bind against the casing.
(Figure 10, Page 21)
The back cover is equipped with a pressure relief valve (27) to provide additional safety
for the pump and operator (refer to
Liquid Temperature And Overheating in
OPERATION ).
It is recommended that the pressure relief valve assembly be replaced at each
overhaul, or any time the pump overheats and activates the valve.
Never replace this
valve with a substitute which has not been specified or provided by Remko.
Periodically, the valve should be removed for inspection and cleaning. When
reinstalling the relief valve, apply 'Loctite Pipe Sealant With Teflon No. 592', or
equivalent compound, on the relief valve threads. Position the valve as shown in Figure
10, page 21 with the discharge port pointing down.
Final Pump Assembly
(Figure 10, Page 21)
Install the shaft key (16, Figure 11, page 23) and reconnect the power source. Be sure
to install any guards used over the rotating members.
15. PRESSURE RELIEF VALVE
MAINTENANCE
Do not operate the pump without the guards in place over the
rotating parts. Exposed rotating parts can catch clothing, fingers, or
tools, causing severe injury to personnel.
DANGER!
Install the suction and discharge lines and open all valves. Make certain that all piping
connections are tight, properly supported and secure.
Be sure the pump and power source have been properly lubricated, see
LUBRICATION .
Remove the fill cover assembly and fill the pump casing with clean liquid. Reinstall the
fill cover and tighten it. Refer to
OPERATION , Section C, before putting the pump back
into service.
