Overview

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).

Function Description

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.

Usage Features

The Wilo-Padus MINI3 is intended for use in domestic environments, specifically for applications involving:

  • Sewage not containing faeces: Suitable for general wastewater discharge from household sources.
  • Wash basins, shower basins, and bathtubs: Effectively drains water from these fixtures.
  • Wastewater with small amounts of sand and gravel: Can handle fluids with minor solid content, though not designed for highly abrasive materials.
  • Rainwater: Ideal for draining accumulated rainwater.
  • Drainage water: General drainage tasks in and around the home.

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.

Maintenance Features

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.

Cleaning:

  • External Cleaning: The pump and cable should be rinsed with clean, running water. Any dirt residue on the floor should be flushed into the sewage drain. After cleaning, the pump should be allowed to dry out.
  • Internal Cleaning: For models with a vortex impeller (MINI3-V), the lower part of the pump housing can be removed to clean the interior and impeller. For models with a multi-channel impeller (MINI3-M), the strainer on the suction port can be removed for cleaning the strainer and impeller. Sharp edges may form on the impeller and suction port, so protective gloves must be worn during cleaning to prevent cuts. The flat gasket should be checked for damage and replaced if necessary.
  • Disinfection: If there is a risk of germ formation, the pump should be disinfected thoroughly after removal. Disinfectant instructions from the manufacturer should be followed, and appropriate personal protective equipment (gloves, face mask, safety goggles, breathing protection mask) should be worn.

Operating Fluid (Oil):

  • The oil in the sealing chamber lubricates the motor and pump side seals. Leakages should be absorbed immediately. In case of major leakages, customer service should be contacted.
  • Oil Change: The oil should be changed after 720 operating hours or once a year. This involves positioning the pump horizontally, unscrewing the sealing chamber screw plug, draining the old oil into an oil-resistant collector tank, and then refilling with new oil of the specified type (ISO VG class 32, e.g., ELFOLNA DS 22 or Shell Turbo T 32). The oil should be checked for metal swarf, which indicates internal wear. The seal ring of the screw plug must be replaced with a new one during reassembly.

General Overhaul:

  • After 1,500 operating hours, a general overhaul by the customer service team is recommended. All components will be checked for wear, and damaged parts will be replaced to ensure continued optimal performance.

Storage:

  • For transport and storage, the original packaging should be used. The pump should be packed dry, as wet or humid pumps can soften the packaging. Recommended storage conditions are between 5 °C and 25 °C (41 °F and 77 °F) with a relative humidity of 40% to 50%.

Safety Precautions:

  • Always wear personal protective equipment (safety shoes, gloves, safety goggles, face mask, breathing protection mask) during transport, installation, removal, cleaning, and maintenance.
  • The pump should always be carried by its handle, never by the connection cable.
  • Electrical connections must be performed by a qualified electrician, adhering to local regulations, and ensuring proper earthing and residual-current device (RCD) installation.
  • If the pump is not used for a prolonged period, it should be switched on and run through one pumping process every two months to prevent encrustations and clogging, provided suitable operating conditions are met. If not, the pump should be removed and cleaned.
