BEST CONTROL

The BEST CONTROL electronic pump controller starts and stops the water pump according the user’s needs.

It replaces the traditional pressure system of tank, pressure switch and float switch, offering more advantages such as:
 
• Easy installations.
• Reduced dimensions.
• Constant flow.
• No maintenance required.
• No need to install pressure tanks.
• Pump protection against dry running, with automatic 
  reset.

The BEST CONTROL electronic pump controller monitors the water pressure and flow rate that runs through it and protects the pump against dangerous working conditions like dry running.
When a tap is opened, BEST CONTROL starts the pump and keeps it running, delivering constant flow. 
BEST CONTROL stops the pump when the demand is near zero.

APPLICATIONS

BEST CONTROL is an electronic pump controller design for water pumps which pull water out of shallow wells, underground tanks, ponds or lakes to be used for:

• Residential boosting systems.
• Irrigation.

BEST CONTROL comes in two versions which only vary in their restart pressure calibrations:

• 22 psi
• 42 psi

FEATURES AND BENEFITS

BEST CONTROL’s body is made of technopolymer.
BEST CONTROL comes with built-in check valve.
Pressure loss extremely low, for this reason it is possible to use BEST CONTROL electronic pump controller with capacity up to 40 gpm (See manual for pressure loss details).
Spring/membrane water accumulator. A special membrane guarantees a high level of protection against overpressure. BEST CONTROL’s high capacity is essential to avoid frequent starts/stops of the pump in case of leaking in the pipeline.
Circuit board: Easy to replace.

JSC 
  
An exclusive diffuser design with fl ow control device provides for compact construction, fast self-priming capability and low noise.

Reliable with new design features the JSC is more robust and forgiving when temporary abnormal operating conditions may exist.

The JSC is smaller than conventional pumps of a similar type, allowing for installation in restricted spaces and providing for easier retrofi t applications.

Fast air evacuation reduces the risk of air-pockets developing at the mechanical seal preventing the danger of seal failure due to a lack of fl ushing and cooling.

The new diffuser and fl ow control device guide the fl uid from the impeller into the central part of the pump casing, reducing turbulence and velocity, with effective use of the surrounding liquid in dampening the noise of fl ow.

APPLICATIONS

For drawing water out of a well.
For lifting water containing air or other gases.
For increasing water pressure from fl ooded suction applications.
As pressure boosting pump for central water systems with low pressure (follow local specifi cations if increasing network pressure).
For garden use.
For clean liquids or slightly dirty surface water.
For washing with a jet of water. 

OPERATING CONDITIONS

Liquid temperature: 32 °F to 95 °F.
Ambient temperature up to 104 °F.
Maximum permissible pressure in the pump casing: 116 psi.
Continuous duty.
