BT-S peristaltic pumps

Economical BT-S transfer pumps with MODBUS communication and high precision — the BT101S, BT301S and BT601S models cover a flow from 0.006 to 2300 ml/min with repeatability better than 0.5%. Four-digit LED display and an RS485 interface.
- RS485 interface with MODBUS — easy integration with SCADA/PLC
- Flow precision better than 0.5%
- Flow from 0.006 to 2300 ml/min (BT101S/301S/601S)
- Speed 0.1–150 / 350 / 600 rpm, reversible direction
- Four-digit LED display of current speed
The BT-S combines an economical price with a feature usually found on more expensive pumps: MODBUS communication over RS485. These are transfer pumps for installations where the operation of several devices is coordinated from a single controller or supervisory system.
Precision and communication
Flow repeatability better than 0.5% makes the BT-S suitable for tasks that need a steady liquid stream — from feeding analysers to continuous dosing. A four-digit LED display shows current rpm, and the RS485 interface with the MODBUS protocol lets you read and set operating parameters remotely, without operator intervention.
Three models, a wide range
The BT101S, BT301S and BT601S differ in maximum flow, together covering a range from 0.006 to 2300 ml/min. A speed precision of 0.1 rpm and reversible direction give control at both very small and large streams.
For analogue 0–10 V control the BT-N fits better; if you want the simplest transfer, the BT-M. Ask for a quote and we will help select the head and tubing.
