INSTALLATION, OPERATION AND MAINTENANCE MANUAL 

 

Installation 

Location 

The pump should be located as near as possible to the liquid 
to be pumped and in no case should the pump be more than 
7m (23 feet) above the surface of the liquid supply.  The 
pump should always be as level as possible. 
 

Suction System 

Connect horizontal suction hose or pipe to suction flange.  
Pipe or hose must be self supporting without adding stress 
to pump body.  If a hose is used, it should be of the 
reinforced type to prevent collapsing under vacuum.  All 
suction system pipe or hose and connections must be free of 
air leaks, as even a very slight leak will greatly reduce 
pumping efficiency and priming ability.  The pump should be 
installed with the trash strainer on the suction line to prevent 
oversize solids from being drawn into the suction system. 
 

Discharge System 

Connect discharge hose or pipe to discharge elbow on top of 
the pump body. 
 

Operation 

Priming 

Remove the flooding cap at the top of the casing and screw 
it back tightly after filling up the casing with priming water.  
(Open the gate valve on the delivery line, if so equipped.)  In 
freezing weather use warm water if possible, to prevent 
damage to internal parts from ice.  At each subsequent start, 
check priming liquid level in pump body since the pump is 
self-priming only when the body is full of liquid.
