PUMP DRIVE CONSIDERATIONS
Conde SDS Series pumps can be belt driven or direct driven with couplings from gasoline or diesel en-
gines, electric motors, PTO drives, or hydraulic motors.
BELT DRIVE SYSTEMS
Pulley combinations should be chosen so that pumps run within the specified speed range. All Conde
SDS Models are made to operate between 1000 and 1750 rpm. Pulleys should be specified that have
adequate “belt wrap” so that maximum contact of belt to pulley can be achieved and minimize the
chance of damage to the pump by over-tightening the belt(s). Please contact Westmoor, Ltd. For infor-
mation on proper pulley combinations and belt sizes for your SDS model and application. Always leave
about 1/2” of belt play when adjusting the belt. Over-tightening the belt can damage the pump and not
enough tension can cause belt slip and loss of pump performance.
DIRECT DRIVE COUPLINGS
We recommend Lovejoy type couplings with a flexible rubber “spider” between the pump mounted
flange and the motor mounted flange. Couplings must be carefully aligned per the manufacturer’s speci-
fications. A small straight edge and set of feeler gauges should be used to insure that the coupling is
aligned properly. Call Westmoor, Ltd. to determine which model coupling is correct for your pump and
application.
UNDER THE HOOD
SDS Series pumps are available in under-the-hood versions complete with electric clutches. These
pumps are designed to be driven off a truck engine. Conde SDS under-the-hood pumps are available
with clutches that accept either v-belt or poly-groove serpentine belt drives. The poly-groove clutches
are availble in either six or eight groove versions. Conde SDS clutch pumps are also available with re-
mote oilers
Due to the many different models and model years of trucks that could be capable of under-the-hood
pump installation, Westmoor, Ltd. can not offer mounting brackets for various trucks. It is up to the pump
installer to determine how the pump is to be installed. General guidelines for proper belt tensioning
should be observed.
