Banjo 301PIH13W Instruction Manual

Read these instructions and the instructions covering the operation of the pump drive unit. Do not
operate the gas engine (if so equipped) until you have put oil in the engine. Do not operate the wet
seal pump until you have filled the wet seal reservoir
submerged) with a 50% ethylene glycol (anti-freeze) and 50% water mixture.
Check the coolant mixture level in the wet seal reservoir after every 5 hours of use, fill reservoir as
necessary. Check oil level in the gas engine (if so equipped) after every 5 hours of use, fill reservoir
as necessary. Change coolant mixture in reservoir after every 100 hours of use or annually, which
ever comes first.
Always fill the pump body with the liquid to be pumped before starting pump. It is not necessary to
drain the pump body after use, unless there is a danger of freezing.
Make certain that all hose and pipe connections are air tight. An air leak in the suction line may
prevent priming and will reduce the capacity of the pump.
Always place the pump as close to the liquid to be pumped as possible. Keep the suction line short
and with few bends. Keep the pump and engine on a level foundation. A poor foundation and a heavy
suction hose (made heavier when "primed" full of liquid) could result in a pump "down the hole".
There are important instructions regarding preparing the engine for long periods without use. (Read
the engine instruction manual). Under these conditions, drain the pump and wet seal. Refill wet seal
with fresh coolant mixture and reinstall fill and drain plugs. Leave all plugs (filter and drain) out of the
pump. Always try to store the unit in a heated and dry building.
When pumping dirty water or other liquids containing solids, always use a pump strainer on the end
of the suction line. There are no points on the pump which need lubrication. The wet seal assembly is
cooled and lubricated by the ethylene glycol/water mixture.
