Often in Australia Mono style PC pumps are commonly used for mine dewatering. The main issues with using PC pumps for mine dewatering are:
- PC Pumps have to be very long to accommodate the high pressures required to bring the water to the surface of the mine – this requires a lot of space!
- PC Pumps have low flow rates when compared to centrifugal pumps. One Ritz HPM pump can do the job of multiple PC pumps so that mines can be dewatered in the wettest conditions.
- PC pumps use rubber stators that wear quickly creating huge ongoing maintenance costs. HPM pumps are 100% axially balanced and have inexpensive replaceable wear parts that protect all important components.
- PC pumps in many cases operate at close to their pressure limits of approximately 48 Bar (lowest design life). Ritz HPM pumps are designed for extreme duty and operate up to 160 Bar (1600m head!)
