MIDI 1600 sewage pumping shaft

Product detailed description

The MIDI 1600 sewage pumping shaft is commonly installed in residential, industrial, and recreational buildings where the layout or terrain prevents direct gravity-fed connection to the public sewer network. This unit is ideal for detached houses, small industrial complexes, and holiday centres where wastewater must be pumped to a higher elevation. The system handles both greywater and blackwater, making it suitable for kitchens, bathrooms, and laundry areas. The compact design allows for underground installation with minimal space requirements. The pump operates automatically, activating when the liquid level reaches a set threshold, and deactivates once the tank is emptied.

For installers, the MIDI 1600 offers a complete solution that requires no additional modifications beyond standard plumbing connections. The unit is designed for direct burial, with a non-load-bearing lid to prevent accidental damage. It is not suitable for high-traffic areas or heavy vehicles. The pump’s shredder ensures that fibrous and solid waste is processed before discharge, reducing the risk of clogging. The system is intended for continuous use in environments with up to five to eight occupants, making it suitable for small households and guest facilities.

Technical parameters

The technical parameters determine the suitability of the MIDI 1600 for specific applications. The 230 V supply voltage ensures compatibility with standard single-phase electrical systems. The 10 m supply cable allows for flexible positioning relative to the power source. The maximum flow rate of 230 l/min indicates the system’s capacity to handle typical domestic usage patterns. The physical dimensions (160 x 100 cm) define the footprint and depth required for installation. These values are essential for verifying whether the unit can meet the hydraulic demands of the site and for planning the electrical and mechanical connections.

Installation and connection

Installation begins with preparing a suitable pit or chamber with a minimum internal diameter of DN 600 mm to accommodate the unit. The inlet is DN 110 mm, but it can be modified to DN 125 or DN 160 mm upon request—this must be specified during ordering. The outlet is DN 50 mm and connects to the main sewer line using standard plastic fittings. The pump is supplied with a check valve to prevent backflow. The unit must be installed in a dry, stable location free from standing water unless the site has a low groundwater level. The non-load-bearing lid must be secured to prevent accidental access. Common installation errors include incorrect inlet/outlet sizing, failure to secure the lid properly, and neglecting to align the pump with the incoming flow path to avoid turbulence and premature wear.

Compatibility and accessories

The MIDI 1600 is compatible with standard domestic and light industrial wastewater systems. It is designed to work with standard DN 50 mm and DN 110 mm piping. Additional components such as inspection covers or access manholes may be necessary depending on the site layout. For maintenance purposes, a secondary IP 400 submersible pump can be ordered separately for cleaning and servicing tasks. This auxiliary pump is not included in the standard package but can be added at the time of order by specifying it in the notes. The unit does not require external control panels or sensors beyond those integrated into the pump system.

Technical background for designers

The MIDI 1600 operates using a submersible WQ 15-7-1,1 pump with a mechanical shredder. The pump is fully submerged within the chamber and activated by a float switch. The shredder reduces the size of fibrous and solid waste before discharge, preventing blockages in downstream pipes. This material choice ensures long-term durability in environments exposed to acidic or alkaline wastewater. The system integrates into existing plumbing networks via standard flanged or threaded connections. The performance of the system depends on the correct sizing of the chamber and the pump’s ability to overcome the vertical lift required to reach the sewer line. The pump’s flow rate and head pressure must be matched to the total dynamic head of the system to ensure efficient operation.

Service and operation

Regular inspection of the pump and shredder is recommended to ensure continued operation. The system should be checked for signs of clogging, unusual noise, or vibration. The shredder should be inspected for wear or damage to its cutting blades. The lid must remain intact and unobstructed to allow for safe access during maintenance. No scheduled service intervals are specified in the product documentation, but the unit should be serviced if performance declines or if the shredder becomes jammed. The auxiliary IP 400 pump can be used to assist in cleaning the chamber during routine maintenance. The system should not be operated continuously under conditions that exceed the pump’s rated capacity, as this may lead to overheating or mechanical failure.

Frequently asked questions

Can the MIDI 1600 be used for industrial wastewater containing chemical residues?
Yes, provided the chemical concentrations are within the limits specified in the manufacturer’s technical data sheet. The polypropylene construction offers good chemical resistance, but highly corrosive substances may affect long-term performance.

Is it possible to modify the inlet size after the unit is installed?
No, any modification to the inlet size must be specified at the time of order. The DN 110 mm inlet can be changed to DN 125 or DN 160 mm, but this requires prior arrangement with the supplier.

Can the pump be manually overridden during maintenance?
There is no manual override function included in the standard system. The pump operates automatically based on the float switch. A separate IP 400 pump can be used for temporary manual pumping during servicing.

What is the maximum vertical lift the pump can handle?
The pump’s head capacity is not specified in the product documentation. This value must be obtained from the manufacturer’s technical data sheet to determine suitability for specific applications.
