The TF series is a tank-mounted suction filter that sits at the pump intake to keep contamination away from the pump and downstream hydraulic components. The filter head stays outside the tank while the suction cylinder is immersed below the oil level, and the unit can be fitted on the side, top or bottom of the tank. A self-sealing valve keeps oil in the tank while the element is changed or cleaned. A bypass valve and a clogging indicator complete the protection set.

Choose TF when you need a robust suction-side filter for hydraulic systems in heavy, mining or metallurgical machinery. Published element precision options are 80, 100 and 180 μm, nominal flows run from 25 to 1,300 L/min, and initial pressure loss is below 0.01 MPa. Models up to 160 L/min have threaded tube connections (M22×1.5 to M48×2); from 250 L/min they use flanges. Indicator switches are listed at 12, 24, 36 or 220 V.

To choose a size, match the nominal flow to your pump, select the element precision for your pump's tolerance to contamination, and decide the connection type and indicator voltage. If your fluid is water-glycol, tell us at the start, because the ordering code carries a separate marking for it. For a different mounting position or other suction filter series, send us your tank layout and we will advise.

Frequently asked questions

Why does the TF suction filter have a self-sealing valve?

The product information states that the self-sealing and bypass arrangement keeps the tank oil from flowing out when the element is changed or cleaned.

How do I read the model code?

In TF-25×*L-C/Y, 25 is the nominal flow in L/min, * is the filtration precision, L means a tube (threaded) connection, and F means flange. The remaining letters are part of the ordering code. Tell us your flow, precision and connection type and we will give you the full code.

Can I get a version for water-glycol fluid?

Yes, the ordering example in the product data shows a water-glycol version with a different marking in the filter and element codes. Please contact us with your fluid to confirm.

What are the minimum order quantity and lead time?

Minimum order quantity and lead time depend on the model, options and order size. Please contact us to confirm.
