The RV-Series
Heavy Duty Submersible Slurry Pumps
Features
Unique concept
The combination of thoroughly-tested slurry pump wear parts and purpose-build
fully submersible electric motor makes the RV heavy duty slurry pump concept
unique in its class.
Low Pressure Seal
The
mechanical shaft sealing is never exposed to the pump pressure, since the
connection between the motor and the pump casing is open. Leakage from the pump
casing is controlled by efficient sealing vanes on the back of the impeller.
Leakage
Monitor
The oil-chamber between the seals provides a buffer against the
surrounding medium, and it is fitted with a leakage monitor to
warn against water penetration. The motor is also fitted with
temperature monitors and a leakage probe for the stator
housing.
Simple Monitoring
The temperature and leakage monitors can be connected to a simple control-box or to an existing monitoring system.
Wear
Parts
The heavy built pump components are identical to those used in the Svedala
(VASA) Vertical and Horizontal slurry pumps, and are designed for highly abrasive tasks. The wear parts are
stocked in SHR, which is a high-chrome/nickel alloy casting, with a hardness in excess of
600 HRB, or coated in natural rubber or polyurethane. Other options are
available for special applications (MetaChrome, 30%
Chromium, Duplex etc...).
Motor
Size
The pump size and motor
speci- fication can be selected to suit the job between
approx. 6,0 ~ 100 kW..
The minimum information required for proper selection is:
- Capacity
- Fluid density and description of any contaminations
- Total discharge head, or a description of the pipe system
