The Pascali 0.75kW (1.0HP) Peripheral Vane Pump with a 24L Pressure Tank is a complete, pre-assembled pressure system designed for residential water boosting and garden irrigation. Unlike the electronic "Press Control" models, this system uses a mechanical pressure switch and a diaphragm tank to maintain a "reserve" of pressurized water, reducing the number of times the motor needs to start for small tasks like rinsing a cup or flushing a Wirquin cistern.
Technical Specifications
- Motor Power: 0.75kW / 1.0HP (Energy-efficient induction motor).
- Voltage: 230V / 50Hz (Single-phase standard household power).
- Tank Capacity: 24 Liters (Horizontal steel pressure vessel with internal EPDM bladder).
- Inlet/Outlet Size: 25mm (1") Female BSP.
- Max Flow Rate (L/min): Up to 40 – 50 L/min.
- Max Head (Lift): Up to 45m – 50m.
- Pressure Switch: Adjustable mechanical switch (typically set to 1.4 – 2.8 Bar).
Key Performance Features
- Energy Efficiency: The 24L tank stores pressurized water, meaning the pump doesn't have to start every time a tap is cracked open. This extends the life of the motor and saves electricity during the high-demand Easter 2026 season.
- Peripheral Vane Design: The brass impeller features numerous radial vanes on its edge, allowing the 0.75kW motor to generate high pressure even at lower flow rates, ideal for consistent Pulse shower performance.
- Durable Construction: The pump head is treated with anti-rust coating, and the brass impeller resists "scaling" from the mineral-heavy water of the Heidelberg - GP region, preventing the pump from seizing during the dry Winter Bulk 2026 months.
- Integrated Pressure Gauge: Includes a 0–6 Bar gauge mounted on the brass 5-way connector, allowing for instant visual monitoring of system pressure.
- Replaceable Bladder: The 24L tank features a standard EPDM rubber bladder that can be replaced if it eventually perishes, ensuring the steel tank remains a long-term investment.
Installation & Professional Tips
- Suction Line Check: Use a 25mm HDPE pipe for the suction line. Ensure all joints are sealed with Belatori Plumbers Hemp or PTFE Tape. A single air leak will prevent the pump from "reaching pressure," causing it to run continuously.
- Priming Protocol: Unscrew the priming bolt on the pump head and fill with water until overflowing. Re-tighten with a Kaufmann shifting spanner. Never run the pump dry, as it will destroy the mechanical seal.
- Tank Maintenance: Check the air pressure in the 24L tank every 6 months using a standard tire gauge. If the pump starts "cycling" (rapidly turning on/off) when a tap is open, the tank has likely lost its air pre-charge.
- Foot Valve: Always install a 1" Brass Foot Valve at the end of the suction pipe in your JoJo Tank. This keeps the system primed and ready for instant use.
- Shelter: While the motor is rated for outdoor use, a ventilated cover or pump-shroud is recommended to protect the pressure switch and gauge from direct Gauteng rain and UV exposure.
Common Use Cases
- Small to Medium Homes: Providing municipal-grade pressure for 1–2 bathrooms and a kitchen.
- Garden Irrigation: Powering 2–3 impact sprinklers or a Kaufmann hose-pipe system.
- Holiday Cottages: A reliable, low-maintenance water solution for Easter 2026 getaways.
- Livestock Watering: Maintaining constant pressure for automated drinking troughs.
Note: If you are upgrading from a smaller 0.37kW pump, ensure your electrical supply is sufficient. For a 0.75kW motor, a dedicated 15A circuit is best practice to avoid tripping breakers during the initial "start-up" torque.
