Constant Pressure System

DynaDrive Constant Pressure SystemModel Numbers: DD60-10(CE), DD90-11(CE)Compact, all stainless steel horizontal multistage centrifugal pump pressure system control options to suit application. Flows up to 140L/min and heads up to 64m.

APPLICATIONSConstant pressure system for:

> Household and domestic water supply > Farming and agricultural water systems > Irrigation and turf watering systems > Automatic general water transfer

WHY CHOOSE THE DAVEY DynaDrive CONSTANT PRESSURE SYSTEM?Horizontal multistage centrifugal pump with all hydraulic parts in stainless steel:• Suitable for high water temperatures• Corrosion & wear resistant• Compact design• Easy to install

Stainless steel impellers with high efficiency impeller profile & thick self-centring impeller neck rings for:• High efficiency• Reduced power consumption:• Low noise output

Air purging valve and stage porting:• Easier priming• Less susceptible to air leaks• Improved dependability

Impellers mounted directly on extended motor shaft:• Maximise performance per stage• High efficiency• Long motor & pump life• Increased wear resistance

Pump casing assembly attached to motor bracket at 8 points with o-ring seal:• Complete stainless casing• Better sealing• Longer service life

Davey built, totally enclosed fan cooled (TEFC) electric motor:• Sealed and greased for life motor bearings• Oversized drive end bearing• Longer life• Easy service• Economical & quiet running

CONTROLLER• Warning indication for system faults• Adjustable pressure settings• Constant pressure at high flow rates• Loss of prime protection• Capable of daisy chain applications of two pumps in parallel• Easy service• Economical & quiet running
