Diaphragm Pump Pneumatic Batch Controller
Our Pneumatic Batch Controller is a versatile and accurate way to dispense a predetermined volume of liquid or gas from your Tapflo Diaphragm Pump. The Pneumatic Batch Controller is available in 2 key variations: predetermining batch control and timed batch control. The predetermining batch control variation (TPUK-BP) uses the number of strokes generated by the pump to control the dispensed volume. The timed batch control variation (TPUK-BT) uses the elapsed time to control the dispensed volume. Additional variations include the TPUK-BPI and TPUK-BTI for internal mounted control to prevent unauthorised adjustments and the TPUK-BP-ATEX for use in hazardous environments.
Features & Benefits
ATEX Batch Controller Features
New features and improvements for the TPUK-BP-ATEX compared to the previous design:
- Temperature class T4 (135°C)
- The enclosure is made from electrically conductive GRP
- Earthing point for dissipation of electrostatic charge – must be permanently connected
- IP66 Rated enclosure and inspection window covering the counter to enable use in washdown environments and chemical environments
- Improved connection sealing via O-Rings to prevent ingress
- Anti-tamper function through screwed locks on the inspection window

To fit a Tapflo Batcher (standard or ATEX), the following parts are required:
- TPUK-B/NV-XX: Blocking Needle Valve (XX = Air Connection Size of Pump)
- TPUK-MU-X: Modified Muffler (X = Output Air Connection, 1″ or ½”)
Optional Extras:
- TPUK-SSR: Remote Start/Stop Controller
Options & Variations
TPUK-BP Variation
Predetermining Batch Control:
- The system records the number of strokes generated by the pump as a series of low-pressure pulses from the air exhaust of the pump. The pump is stopped once a number of pre-set strokes have been achieved, thus controlling the volume of product dispensed by the pump. Volumes generated per stroke can be found within the technical data sheets of the pump in question
TPUK-BT
Timed Batch Control:
- The pump can be started locally or remotely, stopping automatically once the set time has elapsed, thus controlling the volume of product dispensed by the pump
