PV and PVS Piston Vibrator Series
Positive Punch for Difficult Applications
Syntron ® Piston Vibrators from FMC
Technologies assure the flow of materials
through bins, chutes and weigh batchers.
Their cast iron, flat base construction provides
an efficient means of transmitting shock energy
developed by the reciprocating piston
to the mounting surface.
Syntron Piston Vibrators are available in two
models: High impact (PV) and Reduced Noise
(PVS). PVS vibrators (impact against a cushion
of air) can be used where noise is objectionable.
Unlike turbine vibrators, piston vibrators
require lubrication with oil, SAE-10 or lighter.
Lack of oil in the air rapidly wears down the
piston and cylinder wall.
Features and Benefits
I Cast iron, flat base construction.
I One-piece housing
I Flange mounted
I Ideal for use in mining, chemical, concrete,
plastics, steel, foundry and paper industries
I Available in high impact (PV) or reduced noise
(PVS) models
I High thrust reciprocating action of PVS models
permits operation at low air pressures
I High impact, linear force and efficient energy
transfer assures flow of materials through bins,
chutes and weigh batchers
I Linear vibration
I Impacts in both directions
Pneumatic Vibrators
Piston Vibrator Selection
In order to move material in a bin or hopper, the friction
between the material and the bin wall must be broken. Once
the friction is broken, material cannot cling to the sides of
the bin and it will flow out through the discharge. A prime
consideration in selecting the correct piston bin vibrator is
wall thickness. The following formulas calculate material in
the restricted area which is used as a guide to determine the
number of piston bin vibrators necessary.
I Calculate the weight of the material in the transition or
sloping part of the bin. Normally, this is the only place where
the friction between the material and the bin side has to be
broken. Do not calculate the total weight, only what is in the
transition part of the bin.
I For conical bins, calculate as follows:
0.261 x dia. 2 x height x material density in lb/ft 3 (kg/m 3 )
I For rectangular bins, calculate as follows:
Length x width x height x 1/3 x material density.
Chutes
The force required of the vibrator is equal to the weight
of the chute plus vibrator plus maximum material in the
chute. See page 43 for more detail.
