Multifunctional device for 5-30 l/s flow

The compact multifunctional device for a flow rate of 5–30 l / s is designed to remove large fractions of household dirt, crushed stone, and sand from the incoming water and transport them to containers.

Taking into account local requirements and economic aspects, the multifunctional device can be manufactured in a basic version or with additional functions for choice and for different flows.

Basic functions:

  • catching sediments (sand, gravel)
  • retention of dirt on the grate
  • transportation of the captured material to the container
  • integrated bypass

Additional functions:

  • washing waste from the grate
  • dewatering of waste from the grate
  • sand washing


  • possibility of filling with a pump and by gravity
  • integrates all functions of coarse pre-cleaning
  • small installation space
  • gap between rods optionally from 3 to 6 mm


MZ_I is the simplest type of device. Waste from the grate and sediments with heavy fractions are transported into one common container.

MZ_I_5 – Qmax = 5 l / s
MZ_I_10 – Qmax = 10 l / s
MZ_I_20 – Qmax = 20 l / s
MZ_I_30 – Qmax = 30 l / s

MZ_II – designed for wastewater treatment plants where the separation of waste and sediments (crushed stone and sand) is required with transportation in two different containers.

MZ_II_10 – Qmax = 10 l / s
MZ_II_20 – Qmax = 20 l / s
MZ_II_30 – Qmax = 30 l / s
