The Wilo-Padus MINI3 is a submersible drainage pump designed for both stationary and portable wet well installations, operating in intermittent mode. It is engineered for pumping in domestic areas, specifically for sewage not containing faeces, wastewater with small amounts of sand and gravel, rainwater, and drainage water. The pump is suitable for fluid temperatures between 3 °C and 40 °C (37 °F and 104 °F).
The Wilo-Padus MINI3 is equipped with either a vortex impeller (V-type) or a semi-open multi-channel impeller (M-type), both designed for efficient fluid handling. The hydraulics housing and impeller are made of plastic. The pump features a surface-cooled 1~ motor (single-phase) or 3~ motor (three-phase) with integrated operating capacitors and self-switching thermal motor monitoring. This thermal monitoring system automatically deactivates the pump if the motor becomes too hot and reactivates it once it has cooled down, ensuring protection against overheating.
The motor housing is made of stainless steel. A key feature is the oil-filled sealing chamber with a double sealing system: a rotary shaft seal on the motor side and a mechanical seal on the pump side. This design enhances durability and prevents fluid ingress into the motor.
Depending on the model, the pump may come with a detachable connection cable with a fitted plug (CEE 7/7) or a bare cable end for fixed connection to on-site controls. Some models (e.g., Padus MINI3-...-A) are equipped with a float switch, which automatically turns the pump on and off based on the fluid level. The upper floater triggers the pump to turn on, while the lower floater turns it off. Models without a float switch and plug are designed for fixed connections to external controls.
The pump's design allows for easy installation, with options for vertical stationary or portable wet well setups. It includes a handle for convenient transport and positioning.
The Wilo-Padus MINI3 is intended for use in domestic environments, specifically for applications involving:
The pump is not designed for pumping highly flammable and explosive fluids (such as gasoline or kerosene), untreated sewage, sewage containing faeces, drinking water, fluids with hard components (stones, wood, metal), fluids with high quantities of abrasive contents (sand, gravel), viscous fluids (oil, grease), or seawater. Use in potentially explosive atmospheres is strictly prohibited.
For stationary wet well installation, the pump is placed directly onto the pressure pipe, which must be self-supporting. The connection to the pressure pipe should be stress-free and sealed with Teflon tape. It is crucial to install appropriate valves (gate valve, non-return valve) and ensure the discharge pipe is frost-proof. Air pockets in the pump and discharge pipe should be avoided to prevent delivery problems, potentially requiring ventilation systems like an air vent valve. For portable wet well installation, the pump can be placed at any suitable location, secured against falling over, with the pressure hose attached and routed properly.
When operating, it's important to ensure the float switch can move freely (if present) and that the inlet quantity does not exceed the pump's delivery rate to prevent overflow. The pump should never be run dry, as this can damage the seal.
Regular maintenance is crucial for the longevity and efficient operation of the Wilo-Padus MINI3. All maintenance tasks should be performed in a clean, dry, and well-lit environment, using only original manufacturer parts.
