Tohkemy Beta X Chemical Pump

Manufacturer: Tohkemy Corporation
Model: Beta X

Features

A new-generation diaphragm pump
The Beta X is a quiet, stepping-motor-driven diaphragm pump offering high precision, reduced pulsation, and simple, intuitive setup.
Stepping Motor Drive: Delivers smooth, low-pulsation transfer with high control performance.
Intuitive Operation: Set flow rates directly in L/h via click wheel and LCD—no manual stroke length or rate adjustments required.
Easy Installation: Click-in design for quick floor or wall mounting; multi-color LED for distance status/alarm monitoring.
Backflow Prevention: Ensures consistent, unidirectional liquid transfer.

Options

Response to digitization and remote monitoring
Programming and data reading are possible via a smartphone through Bluetooth®/NFC integration.
External signal operation
Pulse signal operation: Operates according to a voltage-free pulse signal from an external source.
Remote ON/OFF operation: Operates/stops according to a voltage-free contact signal from an external source.
Analog signal operation: Operates in conjunction with an external 4–20 mA (0–20 mA) signal.
Two-stage level switch input
Monitors the liquid level of the chemical tank, and issues a warning and stops operation when the liquid level decreases.
Alarm and pacing relays
Alarm relay: Outputs alarms for things like pump failures or low liquid levels.
Pacing relay: Outputs a volt-free contact signal with each pump stroke. Beta X
