Danfoss

The store category Danfoss covers engine and ancillary parts used with hydraulic systems on agricultural, construction and workshop machinery.

The full category path is All products in the shop/Hydraulics & Transmission/Hydraulics/Pumps/Spare parts/Spare parts for piston pumps/Danfoss. It shows where the category sits within the range and helps users select the correct product section.

Application and purpose

Parts in this group support power generation, sealing, lubrication or engine control. A single trade name may cover several designs, so compatibility must be confirmed from technical data rather than from an image alone.

Which subcategories does this section include?

Key subcategories include (store labels):

• Danfoss spare parts series 45
• Danfoss spare parts series H1

How to select the correct product

Start by identifying the machine, equipment or assembly. Then compare the features that most often determine compatibility:

• engine code and version
• OE number
• standard or oversize dimensions
• ancillary version and production date
• machine or equipment make, model and version
• catalogue number, OE number or manufacturer reference

Technical product data shows that several parameters may matter at the same time, depending on the part's function: dimensions, material, temperature range, pressure, flow, voltage, load rating or connection type. An OE or manufacturer reference is extremely useful, but it should still be checked against dimensions and equipment version.

If several versions exist for one model, record the production year, serial number, engine or gearbox code and the marking on the old part. A photograph of the mounting position may help, but it does not replace measurement and specification comparison.

Installation, operation and safety

Engine work requires cleanliness, accurate measurement and the manufacturer's tightening sequence and torques. Refill the correct fluids, bleed relevant circuits and check for leaks after assembly.

For safety-related parts, pressurised systems, electrical work and chemicals, manufacturer instructions, required competence and suitable protective equipment always take priority.

FAQ

How should the correct subcategory be selected?

First identify the machine type and the function of the required part. Then choose the subcategory by system, manufacturer or application and complete the check using the part number.

Does a similar appearance confirm that the part will fit?

No. Similar parts may have different dimensions, threads, materials, operating ranges or mounting sides. Technical specifications should be the basis of the decision.

What should be checked after installation?

Check fixings, leakage, freedom of movement and operation of the relevant system. Testing should be carried out without load or under controlled conditions, in line with the manufacturer's instructions.
