Accessories for pneumatic drive bellows pumps

Pump controller FDC-1

Contact

• The pump discharge rate can be monitored and maintained at a constant level by connecting an electric air regulator (optional) to the pump air supply line. This enables stable flow and filtering even when the discharge load varies due to lncreased filter resistance. In addition, the service life of the bellows will be maximized because the difference between its internal and external pressures is kept to a minimum.
• The controller can monitor the flow rate, the number of strokes, and the total count.
• The unit operates either in the AUTO mode using external signals or in the MANU mode for manual control.
• The flow rate can be set at two different values as desired.
• In addition to the sensor mode using the proximity sensors, the timer mode is included as a standard feature. This enables continued pump operation in the timer mode in case of the failure of a proximity sensor.
• The unit is equipped with various alarm displays and output functions, including leak alarm and a pump malfunction alarm.

Pulse dampeners PD-H (for wet use)

Contact

• A low cost and compact dampener.
• Liquid inside the bellows can be easily drained.
• A leak sensor is included as a standard.

Pulse dampeners PD-H1

Contact

No automatic pressure adjustment.

• The PD-H1 is a medium-pressure design for use with FF, FF-H and FA pumps.

* Models with leak sensors are available through special order.

Automatic dampeners PDA-H1 / PDA-WB / PDA-W

Contact

• Automatic pressure adjustment minimizes downtime, eliminates manual adjustments.
• Liquid inside the bellows can be easily drained. (PDA-WB/W model)
• The PDA-H1 is a medium pressure design for use with the FF, FF-H, and FA pumps. The PDA-WB is a high-pressure design suitable for use with the FW, FW-H, and FS-H pumps. Typical applications include drug delivery and dispensing.
• The PDA-WB/W includes a leak sensor as standard. (For the PDA-H1, a leak sensor is available through special order.)
• For the PDA-WB/W, only the specified liquid pipe joint can fit the model. Please contact us before use to check if your joint is applicable.

Automatic dampeners PDA-100WBN

Contact

• Automatic pressure adjustment minimizes downtime, eliminates manual adjustments.
• Dampener pressure is automatically adjusted to the minimum pulse pressure even if the pump discharge load changes due to a clogged filter. The unit prevents particles being released from the filter and the pimping vibration.
• A leak sensor is included as a standard.

Quick exhaust valve QEV

Contact

• Quick exhaust valves should be installed between the pump and the external solenoid valve. This helps to prevent corrosion of the solenoid valve from return air. It also reduces exhaust resistance to allow the bellows to move smoothly through each cycle.
