Simplex Suction Filters

Suction filters are used as safety filters to protect pumps in the circuit. Filters with a filtration rating of > 25 μm are widely adopted to avoid negative pressure and sudden pump failure.

These simplex strainers are horizontally or vertically mounted to the reservoir, below the oil level.

  • Flow rates up to 1300 l/min
  • Inline or tank mounting filters
  • Aluminum cast and Buna-N seals
  • Thread or SAE flange connection
  • A Clogging indicator on the filter head
  • Easy installation, simplified pipeline

There is a check valve and bypass valve inside the suction strainer of the pump to prevent return flow of dirty oil into the reservoir during maintenance or when changing elements.

For cleaning, the filter bowl together with suction strainer elements can be taken out of the hydraulic suction filter head.

The die-cast aluminum head and body ensure strength and durability, making these hydraulic suction strainers ideal for a wide variety of mobile and in-plant applications.
