For a metal scrap baler, the brand of oil pump can vary depending on the manufacturer, model, and configuration of the machine. Some balers may use pumps from well-known hydraulic component manufacturers, while others may use pumps supplied by the baler manufacturer itself.

Here are a few common possibilities:

1. Major hydraulic pump brands often used in industrial machinery:

Bosch Rexroth – A leading supplier of hydraulic components.

Parker Hannifin – Widely used in industrial hydraulics.

Kawasaki – Known for high-performance hydraulic pumps.

Eaton (formerly Vickers) – Common in heavy-duty hydraulic systems.

Danfoss – Especially in mobile and industrial hydraulics.

HAWE Hydraulik – German brand known for robust pumps.

Yuken – A popular choice in Asian-made machinery.

2. Factors affecting the pump brand:

Balers from Europe or the US might use Rexroth, Parker, or Eaton pumps.

Balers from Japan or South Korea might use Kawasaki or Yuken pumps.

Chinese-made balers may use domestic brands or the above international brands depending on the price point.

Older or refurbished balers might have pumps that were replaced with a different brand during maintenance.

3. How to determine the exact brand for your machine:

Check the pump nameplate – The pump itself usually has a label showing the brand, model, and serial number.

Consult the machine’s manual – The parts list or hydraulic diagram should specify the pump brand and model.

Contact the baler manufacturer – For example:

Metso, Lindemann, Hammel, Sierra, Maren, or American Baler for large scrap balers.

Smaller or regional manufacturers might use pumps from local hydraulic suppliers.

Ask a hydraulic service technician – They can often identify the pump by its appearance, mounting, or part number.

4. Replacement considerations:

If you need to replace the pump, note:

The original brand and model are ideal for compatibility.

Cross-referencing with equivalent pumps from other brands is possible but requires hydraulic system expertise.

System pressure, flow rate, mounting style, and shaft size must match.

If you provide the brand and model of your metal scrap baler, I may be able to give more specific information about the typical hydraulic pump used.
