Q6: Is this pump reliable in high ambient temperature, dust and sand?
A: The pump is built with hardened internals and heat-resistant seals for continuous duty. For Middle East, Africa and Southeast Asia job sites we recommend keeping the hydraulic oil clean and the fan circuit filter serviced; we can advise on the correct oil grade for your climate.

Q7: How does it behave in cold climate and winter start-up?
A: For Russia, CIS and North America winter operation the pump works with the oil grade specified by the machine manufacturer. We can recommend a viscosity grade suitable for low temperature start-up to protect the pump during warm-up.
