Check compatibility of the hose material with the product being pumped – this should have been
verified by your distributor
• If not already shimmed, shim the pump according to the operating pressure required,
following the procedure described in Section 4.6 on ‘Shim Installation’;
• Check the level of lubricant;
At all times the pump housing needs to be between one third to one half filled with
VERDERLUBE lubricant (this can be verified by use of an external lube level plug fitted to later
models*)
Check compatibility of the lubricant with the product being pumped; VERDERLUBE is a specially
formulated food grade lubricant containing glycerine. In most cases this is a very stable
compound, but can react when mixed with certain types of substance.
Do not use VERDERLUBE with nitrogenous compounds, concentrated acids or strong oxidizing
agents
If you are unsure of the chemical compatibility of your product with VERDERLUBE, your
VERDER distributor will offer advice and if necessary, supply an alternative such as
VERDERSIL, a silicone oil based lubricant

Check all nuts and bolts are tightened to the required torque settings in `Parts List`
• Before connecting the pump to pipe work, run the pump dry for 10 - 20 revolutions in both
directions to ensure that the hose is secured properly. Stop the pump immediately if there
are any leaks or other problems
• Connect the pipe work and tighten all fasteners securely
• Close all drainage taps and open all valves
• Start the pump running for 10 - 20 revolutions. Stop the pump immediately if there are any
leaks or other problems
• Test pump for leaks and back flow at operating pressure and correct flow rate, as it may be
necessary to adjust shimming
