INSTALLATION AND USE

Suitable for use in civil and agricultural applications. The high
eciency and continuous duty capabilities makes these pumps
ideal for use in activities such as ood and spray irrigation, drawing
water from lakes, rivers and wells, or for any number of dierent
industrial applications where the characteristics of high ow rates
and mid to low head are required.
The pump should be installed in an enclosed environment or
sheltered from inclement weather.

OPTIONS AVAILABLE ON REQUEST
