APPLICATION
Thesepumpsmaybedirect-coupledorbeltdrivenfromasuitable
powersource-electricmotor,gasengine,etc. Theyareintended
for installations where the vertical distance from the pump to
water surface does not exceed 7.5m (25 ft.). In all installations,
friction losses in the piping must be taken into consideration.
Pump models ACT-5SD and ACT-6SD should not be used for
pumping liquid fertilizer. Pump model ACT-8SD can be used for
liquid fertilizer if equipped with the high temperature (Viton) seal.

INSTALLATION
(a) LOCATION: Thepumpshouldbeinstalledinalocationthat
providesadequatedrainage,roomforservicing,andprotec-
tionfrom freezing.Aproperfoundationisnecessarytomain-
tainthealignmentbetween pumpandpowersource. To re-
duce friction losses and provide maximum capacities, the
locationofthepumpshouldbesuchthataminimumofsuction
pipingisrequired.
(b) SUCTIONPIPE: Itisrecommendedthatonlynew,cleanpipe

awayfromthesourceofwatersupply,thesuctionpipeshould
beincreasedbyonesize.Thesuctionpipemustalwaysslope
upwards from the water source to the pump to avoid air

be led almost horizontally to the pump. Non-toxic thread

should be thoroughly tightened. A foot valve should be con-

submergedat all times.

b) DISASSEMBLY:(Refer toFig. 2 & 3)
- Disconnect power source from transmission and remove
suctionand dischargepipingprior toanydisassembly.
- Removefour3/8"nutssecuring casing(1)to transmission

(c) REASSEMBLY: (Refer to Fig. 2 & 3 and Repair Parts List)
- Carefully clean all parts. Replace parts showing signs of
excessivewear.Applyfilmoflightoiltobearings,shaftand
on the inside of transmission housing.
- Apply alightsoapylubricantontotherubberonly sealseat
and press into housing (ACT-5SD,-6SD or seal plate
ACT-8SD). Make sure that the seat is seated properly.
- On ACT-5SD,-6SD, install flinger (8) on threaded end of
shaft/bearing unit (3), press unit into housing and install
snap ring (5).
- On ACT-8SD, press outerbearing (14) into housing (2).
Press inner bearing (15) onto threaded end of shaft.
Press shaft and bearing assembly into housing. Care
must be taken to avoid preloading bearings. Install snap
ring (16) and seal (l3) into housing. Slide flinger (8) onto
shaft. Prior to installing sleeve (11), apply liquid gasket to
area of shaft which will be covered by sleeve. Install seal
plate (10) to transmission.
- Install rotating mechanical seal onto shaft with the shiny
side of the washer facing towards white ceramic seat.
Install impeller securely (4) on ACT-8SD. Fasten with
1/4" NC x 1" bolt (9).
- Install gasket (6) and casing (1) to assembly using (4) 3/8" NC
nuts and lockwashers.
- Ensure shaft turns freely and reconnect piping.
