Variant-Specific Benefits
JP – The Pump (Standalone)
The basic JP variant provides essential self-priming jet pump functionality:
- Self-priming capability with suction lift up to 8 metres
- Ideal for manual control installations
- Flexible configuration options
- Compatible with external controls and accessories
Best For: Applications where external control systems are already in place or manual operation is preferred.
JP PT – The Pump with Pressure Tank
The JP PT combines the jet pump with an integrated pressure tank system:
- Automatic start-stop controlled by pressure switch and pressure tank combined
- Pressure tank limits the number of start/stop routines
- Water stored in tank can be used without starting the pump
- Reduced pump cycling extends motor life
- Consistent pressure delivery
Best For: Standard domestic water supply applications requiring automatic operation with minimal pump cycling.
JP PM – The Pump with Pressure Manager
The JP PM represents the most advanced variant with intelligent control:
- Automatic start/stop controlled according to consumption by intelligent Pressure Manager
- Dry-running protection automatically stops the pump in case of dry running
- Anti-cycling (leakage detection) starts and stops pump periodically in case of minor leakages or unclosed taps
- Pressure indication for system monitoring
- Integrated non-return valve eliminates separate installation
- Alarm indication for fault notification
Best For: Applications demanding maximum protection, intelligent control, and comprehensive system monitoring.
Key Features & Benefits
Self-Priming Technology
Featuring a suction lift capability to 8 metres, the JP jet pumps are ideal for transferring water from wells or ground tanks in a large variety of installations. The built-in ejector with guide vanes ensures optimum self-priming properties without manual priming requirements.
Robust Design
Excellent corrosion resistance is ensured by the stainless steel (AISI 304) pump housing and composite impeller, along with paint application by electrophoresis on the motor stool. This construction delivers long service life even in demanding environments.
Thermal Overload Protection
Single-phase models have built-in thermal and current protection with no additional motor protection required. This integrated safety feature prevents motor damage from overheating or electrical faults.
Stable Operation
The hydraulic construction ensures excellent suction capacity even when there are air bubbles and small sandy impurities in the water. This tolerance for imperfect water conditions makes the JP range suitable for real-world domestic installations.
