FP HIGH EFFICIENCY PISTON VIBRATORS

The FP and FPLF series pneumatic piston vibrators produce a linear vibration with adjustable amplitude and frequency.

                FP series needs a standard airline lubrication.
                                                   FPLF series is completely lubrication free.

The frequency is controlled by adjusting the air pressure.
A spring is used in the vibrator to assist starting.
Minimum operating pressure 30 PSI

Easy to install and designed to work continuously under the most demanding conditions.

With proper muffler these units are very quiet and usually at a low noise below 75 dBA.

Explosion proof, light weight and compactness make these units ideal for most applications.

The FPLF, being lubrication free, discharges no oil mist into the atmosphere.

The aluminum body is hard coated and it is corrosion resistant.

There is no paint to flake off.

The high power-to-weight ratio of the unit makes it particularly efficient for feeder applications.

Estremely low air consumption

TECHNICAL DATA
Unbalance Weight: Bronze Piston
Lubrication: Necessary (Oil ISO VG5 = 5 cSt/40°C or distilled water)
Air Supply: 30 to 90 PSI
Air Type: Clean, 5 µm filter required
Body: Aluminum, block anodized and teflonized
End Cap : Aluminum socket with metric mounting thread plastic or aluminum end cap
Max Vibrator Temperature: 250° F (=125° C)
Noise Level Range: 57 to 74 dBA with muffler

ADDITIONAL TECHNICAL INFORMATION

The FP-series vibrators are non impacting so the piston does not hit the socket, but rather stops on an air cushion formed in the respective chamber (socket or end cap side). The force/time curve is therefore relatively sinusoidal without peaks.
This feature is excellent whenever parts have to be moved.

The housing has a female metric thread in the aluminum socket so the vibrator can be easily mounted. The air inlet port in the body as well as the exhaust port in the end cap are tapped with BSP thread (British Standard Pipe) but will accept US NPT (National Pipe Thread) as well. 

 The maximum ambient operating temperature is 50°C = 120°F

Piston vibrators with aluminum end cap may be operated at higher temperatures, but the vibration power will decrease due to increased leakage.

The noise level is extremely low, from 57 to 74 dBA.

Applications

The FP-series piston vibrators are used mainly for feeding materials mounted on chutes, spiral chutes and channels:

  • Feeding of chemical powder in tube channels
  • Feeding of flour, sugar, etc. in the food industry
  • Feeding of small parts into machines
  • Feeding of seed and grain in the flower and vegetables industries

Installation / Operation

The FP-piston vibrator can be placed in any position.

An air line filter with five micron ( 5 µm ) is required to keep dirt from entering and blocking the piston.

A lubricator filled with oil (ISO VG5 = 5 cSt/40°C) or distilled water should be used to avoid abrasion.

Although intermittent operation is possible without lubrication if the operation factor is less than 20%, we do strongly recommend that you always lubricate.

Please note that when mounted in upright position it will take up to two seconds for the piston to move back to its end position after the air pressure is cut down because the piston has to move air out of the housing with the help of the starter spring. If the vibrator will be operated intermittently, the starter spring should be turned to the upper side so that gravity supports the spring.
