Installation
It is important that the AC+ Dry Blender be installed within 3 feet (1 meter) of the liquid
source. The supply piping should be short with a minimum number of elbows and fittings
that impact flow of the liquid into the blending chamber. An eccentric reducer is
recommended at the liquid inlet of the blender. The need for future cleaning and
inspection should be considered when installing the blender.
A supply pump is required to feed the liquid to the blender. A discharge pump may also
be required for certain applications. Contact Ampco Pumps for supply and discharge
pump recommendations.
The adjustable legs should be installed to the base of the unit and the blender should be
positioned where the blending operation will take place. Use a wrench to adjust the legs,
one at a time, until the unit is level.
Connect the supply and discharge piping, making sure each is positioned correctly and
properly supported. Incorrect piping may result in strain on the blender casing. The
AC+2116 model has an 1 ½ inch (38.1mm) liquid inlet, 2 inch (50.8mm) powder inlet,
and 1 ½ inch (38.1mm) liquid outlet. The AC+3218 model has 1 ½ inch (38.1mm)
liquid inlet, 3 inch (76.2mm) powder inlet, and 2 inch (50.8mm) liquid outlet. The
AC+4329 model has a 2 inch (50.8mm) liquid inlet, 4 inch (101.6 mm) powder inlet, and
3 inch (76.2 mm) liquid outlet.
The purchaser is responsible for supplying and installing all piping. Liquid inlet
piping should be short and provide a direct route into the blender. There should be
a minimum number of elbows and fittings in the supply piping. Elbows in the liquid
inlet piping will produce increased friction in the line which will result in cavitation in
the blender casing. Cavitation will result in vibration, noise, poor performance, and
possible damage to the blender. It is recommended the pipe diameter at the inlet be
increased in size where possible. Using an eccentric tapered reducer in place of a
concentric reducer at the inlet will help direct the flow to minimize turbulence.
It is possible to order the blender with an electrically controlled Butterfly valve. The electric
valve should be wired to an auxiliary 110V power source. This will allow the valve to
operate separately from the blender motor so it may be closed if the motor fails. If the power
source to the Butterfly valve also fails, it should be possible to manually override the valve
by applying a wrench to the flats on the coupling adapter.
