FAQS
- How do I reduce the noise level of my Danfoss D25 cast iron gear pump?
Installing the Danfoss D25 cast iron gear pump in a soundproof enclosure is a great way to reduce noise levels. Additionally, adding shock absorbers (such as rubber mounts) can also help isolate vibration and dampen sound. And finally, using oil with low viscosity will reduce any internal friction, resulting in a quieter operation.
- What is the maximum speed that the Danfoss D25 can handle?
The Danfoss D25 offers incredible performance, with maximum speed capability up to 3,000 rpm. This makes it a great option for any job that requires a fast, reliable and cost-efficient solution. With noise levels as low as 76 dB(A), the Danfoss D25 will ensure a quiet operation even when operating at its peak speeds.
- What is the maximum flow rate of the Danfoss D25?
The maximum flow rate of the Danfoss D25 is up to 10 GPM (Gallons Per Minute) with a maximum pressure rating of 455 PSI (Pounds per Square Inch). It is designed for both high and low viscosity fluids, and is ideal for variable speed applications. With its robust construction and efficient design, the Danfoss D25 will help you get your project done efficiently.
- What is the maximum operating pressure for the Danfoss D25 Gear Pump?
The Danfoss D25 Gear Pump has a maximum operating pressure of up to 20 bar (290 psi). This makes it an ideal choice for applications that require high pressure capabilities. The pump is also designed with a robust cast iron housing and corrosion-resistant internals, making it well suited for tough working environments.
