The Pascali 0.75kW (1.0HP) 230V Peripheral Vane Pump with an Inline Flow Switch is a specialized water boosting solution designed specifically for applications where a constant, automatic supply is required, but space or system design prevents the use of a traditional pressure tank.
Unlike a pressure switch, the Flow Switch triggers the pump based on the physical movement of water, making it an ideal choice for boosting low-pressure municipal or tank-fed lines in the Heidelberg - GP region.
Technical Specifications
- Motor Power: 0.75kW / 1.0HP (High-efficiency induction motor).
- Voltage: 230V / 50Hz (Single-phase).
- Max Flow Rate (L/min): Up to 45 – 50 L/min.
- Max Head (Lift): Up to 45m – 50m.
- Switch Type: Magnetic Flow Sensitivity Switch (Automatic On/Off).
- Inlet/Outlet Size: 25mm (1") Female BSP.
- IP Rating: IP44 (Splash-proof motor housing).
Key Performance Features
- Automatic Flow Activation: The pump activates as soon as it detects a flow of roughly 1.5 to 2.0 L/min (e.g., opening a single Pulse shower head or kitchen tap). It remains running until the tap is closed and the flow stops.
- Zero-Pressure Starting: Because it relies on flow rather than a "cut-in" pressure, it is excellent for gravity-fed systems where the "static head" pressure is too low to trigger a standard electronic press control.
- Brass Impeller: Features a heavy-duty brass impeller that resists the mineral scaling common in Gauteng groundwater, preventing the pump from seizing during the dry Winter Bulk 2026 season.
- Thermal Overload Protection: The motor includes an internal thermal cutout to prevent burnouts during high-demand periods like the Easter 2026 holidays.
- Quiet Operation: The 0.75kW motor provides a balanced power-to-noise ratio, making it suitable for residential installations near bathrooms or sculleries.
Installation & Professional Tips
- Mounting Position: The flow switch component must be installed vertically on the discharge (outlet) side of the pump. The internal magnetic "paddle" relies on gravity to return to the "Off" position when water stops flowing.
- Priming Protocol: Before the first run, unscrew the priming bolt on the pump head and fill the chamber with water. Tighten with a Kaufmann shifting spanner. Running the pump dry will destroy the mechanical seal.
- Suction Integrity: Use 25mm HDPE pipe for the inlet. Ensure every joint is sealed with Belatori Plumbers Hemp or PTFE Tape. Even a tiny air leak can cause the pump to lose prime and fail to trigger the flow switch.
- Inlet Height: For the flow switch to work effectively, there must be at least a small amount of "gravity flow" (at least 0.5m of height difference) to move the internal paddle when the tap is opened.
- Electrical Safety: Connect the pump to a 15A circuit with an Earth Leakage protector. Ensure all wiring is housed in a waterproof conduit to protect it from the intense Heidelberg sun and rain.
Common Use Cases
- Low-Pressure Boosting: Increasing shower and tap pressure in homes with low-set gravity tanks.
- Solar Geyser Supply: Ensuring a consistent flow of water to solar heating panels on the roof.
- Garden Irrigation: Powering a small set of Rain-Jet sprayers or a Kaufmann hose-pipe system.
- Industrial Rinse Stations: Providing automatic water flow for small-scale workshop cleaning.
Pro Tip: If the pump continues to run after the tap is closed, it usually means the internal magnetic paddle in the flow switch is stuck due to grit or lime-scale. Simply unscrew the switch housing and clean the internal components with a Shield Microfibre Cloth and a splash of white vinegar to restore smooth operation.
