Smarter Pressure Pump Management with the PressureWatcher
The controller manages water-system pressure while monitoring electrical and mechanical conditions that affect reliable pump operation. A standard pressure switch connects to the dedicated Switch input to control the pressure pump as required.
Intelligent monitoring distinguishes normal operating variations from conditions requiring protective action. This coordinated approach combines pressure control and equipment protection rather than relying solely on a conventional pressure switch.
Suitable Pumps and Applications
The controller supports single-phase and three-phase borehole pumps, surface pumps, and general water pumps within pressure-controlled systems. It also works with borehole and other water-pump controls wherever the installation requires pressure management.
Furthermore, the design accommodates different motor types used within suitable pressure-system pump applications. One controller model covers different pump and motor sizes when installers configure the correct operating parameters onsite.
Easy Two-Button Setup for the PressureWatcher
- Enter preset mode safely using the simple two-button process.
- Set the operating parameters according to the connected motor and pump specifications.
- Store the parameters to support reliable operation and help minimize unnecessary nuisance tripping.
Installation requires minimal supporting equipment, provided all preset parameters remain within the relevant equipment specifications.
PressureWatcher Expert System
An integrated Expert System operates continuously in the background without requiring routine user input. The technology automatically adapts as electrical supply conditions and motor loads change during pressure-system operation.
In addition, an expert motor-load management algorithm addresses operating characteristics specifically associated with pressure applications. This intelligent approach manages demanding conditions without requiring users to continually adjust controller settings.
Managing Challenging Pump Conditions
Pressure systems can encounter weak water sources, transient overloads, over-pumping, overcurrents, and unstable electrical supplies.
The controller actively manages these conditions while allowing the widest possible practical voltage fluctuation range. Moreover, weak borehole applications can make maximum practical use of available water while receiving over-pumping protection. Automatic management also anticipates transient overload conditions and limits destructive effects associated with excessive currents.
Electrical Supply Monitoring
Supply voltage and motor current are continuously monitored to protect the pump motor and support reliable operation.
- Smart voltage monitoring allows manageable fluctuations without unnecessary interruptions when operation remains safe.
- Dynamic current monitoring detects abnormal electrical behaviour.
- Startup stabilization allows voltage and current to settle for appropriate motor starting characteristics.
Comprehensive Motor and Pump Protection
Multiple protection functions work together to identify electrical, hydraulic, and load-related conditions that could damage equipment.
These functions provide broader protection than pressure switching alone can offer within demanding water-pressure applications.
Key protection capabilities include:
- Supply voltage monitoring identifies electrical conditions that could threaten safe pump operation.
- Dynamic current monitoring tracks motor behaviour and detects excessive continuous overcurrents.
- Shaft-load monitoring helps identify abnormal mechanical or hydraulic operating conditions.
- Dry-running detection responds when insufficient water creates harmful pump conditions.
- Bad-connection detection helps identify electrical connection problems affecting reliable operation.
- Rapid-cycling protection reduces repeated switching that can contribute to motor overheating.
- Overcurrent management limits destructive effects associated with excessive electrical current.
Why Pressure Switches Need Protection
A conventional pressure switch starts and stops the pump as system pressure moves between predetermined switching levels. Pressure switches use hysteresis, which creates a difference between their pump starting and stopping pressures.
However, pressure control alone cannot provide comprehensive protection against electrical fluctuations or abnormal system behaviour. Faulty operation or system failure can also cause rapid cycling, repeatedly starting and stopping the pump.
Managing Rapid Pump Cycling
Frequent pump starts can increase motor heat and place unnecessary stress on pressure-system equipment.
PressureWatcher helps protect the system by:
- Reducing rapid cycling automatically when operating conditions require intervention.
- Monitoring cycling behavior and recognizing when it could become harmful.
- Providing an additional layer of protection where conventional pressure systems may require an extra pressure tank to reduce excessive switching.
Standard Pressure Switch Compatibility
The system works with a standard pressure switch and non-return valve, keeping these functions separate rather than combining them into one assembly.
This flexible setup allows:
- Dedicated switch control: The Switch input receives the signal required to control motor operation.
- Flexible component placement: Installers can position components according to specific hydraulic, electrical, and monitoring requirements.
- Easier system design and upgrades: The separated arrangement provides valuable flexibility across different pressure-system installations.
Optimal Controller Positioning for the PressureWatcher
Installers can place the electronic controller where users can easily see its comprehensive indicator display. Operating status, warnings, and recognized fault conditions remain visible without repeatedly accessing inconvenient pump locations.
In addition, users can monitor system information without crawling, kneeling beside hidden equipment, or unnecessarily going outside. Convenient visibility provides earlier awareness of problems that could otherwise cause damage or interrupt the water supply.
Correct Pressure Switch Positioning
Installers can place the pressure switch where it measures system pressure effectively and responds correctly. Positioning the switch close to the pump outlet supports suitable pressure response and effective system operation. Additionally, separating the switch from the controller prevents display visibility from determining the pressure switch location.
Each component can therefore occupy the position best suited to its individual purpose.
Correct Non-Return Valve Positioning
Borehole installations allow flexible non-return valve positioning to suit the system’s hydraulic requirements.
- Above-pump placement: The non-return valve can be positioned above the pump where required by the system arrangement, helping prevent the rising main from emptying after the pump stops.
- Independent positioning: Valve placement can be determined by hydraulic requirements rather than the controller’s location.
- Practical installation: Correct component positioning supports a more practical installation without unnecessarily combining unrelated functions.
PressureWatcher System Diagnostics
Clear diagnostics help users and technicians understand system conditions before, during, and after operating problems.
The controller provides continuous protection by:
- Before startup: Checking conditions and preventing switching if the motor or pump could be damaged.
- During operation: Continuously monitoring voltage and current without unnecessarily interrupting acceptable pump operation.
- After a detected fault: Activating a timing mode when load, current, or voltage faults occur.
- During severe faults: Recognizing when safe operation is no longer possible and locking out further operation.
Visible Warnings and Operating Status of the PressureWatcher
A simplified display communicates controller operation and provides visible warning and fault information. The comprehensive indicator system continuously shows the operating status of the controller. Consequently, users can identify developing problems before they potentially cause equipment damage or unexpected water-supply interruptions.
Accessible status information also removes much of the uncertainty associated with diagnosing pressure-system behaviour.
Operational Data Logging
The controller logs operational data while the pumping system runs. Recorded information provides useful context when technicians investigate electrical faults, unusual operation, or changing pump behaviour.
In addition, this information supports faster and more versatile technical assistance when troubleshooting becomes necessary. Data logging complements visible diagnostics by providing deeper operating information for technical support.
Benefits of Intelligent Pressure Management
Reliable pressure management helps maintain water availability while protecting pump motors from abnormal operating conditions. The system combines automatic protection with intelligent management, reducing the need for user intervention. Fewer nuisance trips help keep water available when operating conditions remain within acceptable limits, while visible diagnostics clearly show users what the pressure system is doing.
