Pressure Booster

Pressure Booster

Inside is a high performance Aquatec diaphragm pump with integrated pressure switch.

Self-contained and easy to handle pressure boost unit, featuring an Aquatec diaphragm pump.

 

A self-contained, easy to handle, and fully automatic pressure boost unit.

The pump operates automatically to boost pressure to attached equipment, giving a maximum line pressure of 4 Bar. The pressure switch ensures it activates only on demand, and when the outlet pressure drops below 2.5 Bar (approx). It will deliver a flow rate in the range 3 - 5 litres per minute. Other flow rates are available on request.Integrated carrying handle to make transport more convenient

 

 

 

 

 

An additional EMC filter to reduce electronic interference can be fitted if the unit is going to be installed anywhere close to sensitive electronic equipment.

The unit can also be fitted with a 12v or 24v DC motor for use in caravans, boats, or anywhere mains voltage is not available. Call us to discuss pricing and options available.

Features:

  • Features a light-weight plastic case with convenient, integrated carrying handle.
  • Comes with external 3/8" push-fit connections.
  • 3/4" BSP conversion kit available as a separate item.

 

  • Fitted with a two metre long, 13 Amp sealed lead as standard. (The lead can be printed with custom text for a small additional cost.)

Performance

Max. liquid temp:

170°F (77°C)

Priming capability:

9 feet

Flow Range:
    Open flow:
    At 4 bar (60 psi):

5 litres per minute
3 litres per minute

Performance measured with flooded inlet (0 psi), 70°F (21°C) ambient and water temperatures and voltage controlled at 230v AC, 60 HZ. Positive inlet pressure will increase the discharge pressure by a similar amount for a given flow. Maximum inlet pressure is 60 psi.

 

Heat Rise

At 60psi discharge pressure, the current drawn is around 0.35 amps. The shaded area in the heat rise chart shows continuous operation. Above 0.39 amps (around 80 psi discharge pressure), the unit is required to shut down intermittently while the motor cools.

Some applications require maximum flows at high pressures for relatively short periods, however, so an explanation of thermal protection follows:

1. The heat rise graph plots the highest current that can run without ever leaving the shaded area, in this case, 0.39 amps. All pumps with lower operating currents may also run continuously, unless the surrounding air temperature exceeds 70°F (21°C).

2. The motor driving this pump has a built in thermal protector that will open, shutting off the pump, when the surface temperature of the motor heats to approximately 145°F.

3. Motors of this size and construction require 20 to 40 minutes of cooling time before the thermal protector closes and re-energizes the pump. Lower current levels heat more slowly, allowing longer run times, but the cool down time still averages about 30 minutes, at 70°F ambient temperature.

4. Your application may call for short bursts of water, consuming far less than the 22 minutes of sustained operation. Start up current exceeds normal running current, however, so cycling should be limited to 6 times per minute.

ALL PERFORMANCE AND HEAT RISE FIGURES ARE APPROXIMATE. ACTUAL VALUES WILL VARY WITH AMBIENT CONDITIONS.
