Optimising output

Maximum output rate is dependant on various factors when pumping resin systems. The

following factors should be taken into account in order to achieve maximum mixed output.

1. Supply of air to the machine.

An air supply of sufficient pressure and volume flow rate must be supplied to the machine. To

check supply is sufficient, ensure that incoming air flow is at least 1200 litres/min at 8 bar

2. Resin viscosity.

High viscosity resins will reduce the potential output of any metering machine for a given

power input. Viscosity of the resin can be decreased by a) increasing the temperature. b)

Reducing filler loadings. c) Using viscosity modifiers

3. Pipe work restriction from pump to mixing head.

Fitting larger bore output hoses, or reducing the hose length can improve output of the

machine. This is an important criteria if long hoses (> 4 metres) or higher viscosity resins are

used.

4. Fillers

When using fillers, it is essential that the filler is well mixed and not allowed to settle out over

a period of time. A tank agitator may be used. Alternatively regularly recirculate the resin.

This may however reduce pump seal life. Filler particle sizes of 5m or less should be used. If

filter blockage is occurring, a larger mesh size should be used. Contact Magnum Venus
