PumpGuard duo

Product catalog summary

Overview
The PumpGuard duo control unit is a compact and modular design intended for pump stations with single or duplex pumps, supporting both 1- and 3-phase systems. It offers a cost-effective solution with features typically found in more expensive models.

Key Features

Compact design with separate battery and input modules.
Digital 3-phase current monitoring and thermal protection inputs.
Operating hours counter and alarm outputs (potential-free and 230VAC).
Level measurement inputs compatible with common Zener barriers.

Level Measurement Options

Diver’s bell/pressure sensing for reliable level detection.
Float switches for single-pump operation, with the option to add more via input module.
Analogue pressure probe (4-20mA) for additional input module connection.

Pump Monitoring and Security

Digital evaluation of pump current consumption across all phases.
Monitoring of reversible and irreversible temperature sensors.
Maximal pump runtime checks for added security.

Special Pump Behavior Settings

Startup timeout and overcurrent retry delay settings.
Overtravel duration and forced pumping to prevent fat crusts.
Forced operation timeout to prevent odors.
Single pump operation restriction at high levels.

ATEX Mode
The PumpGuard supports ATEX conformity through minimal pressure monitoring and compatibility with Zener barriers for digital and analogue inputs.

Mains Failure Signaling
Equipped with a rechargeable battery module and low energy LED alarm beacon, the PumpGuard can signal mains failures for over 72 hours.

BONNEL TECHNOLOGIE Control unit for single and duplex pump stations PumpGuard details The PumpGuard is designed as a compact control unit with the features of a "big" pump controller for the price of a small one. Therefore, a lot of handy features, that are normally not available at this price range, have been integrated. Level measurement possibilities As standard option, level measurement is performed by diver's bell / pressure sensing. This is a very efficient and reliable way to detect the preset switching levels. This measurement can be combined with one alarm float switch. A second option...
