Pressure Pump #5806232

Applications

Fully automatic variable speed units, for commercial and domestic applications. ESPA In-Line Inverter booster sets are designed to provide an efficient solution to water boosting applications where existing supplies are unreliable or insufficient to meet the demands of commerce and industry. ESPA variable speed booster sets embrace the best in modern control techniques, whilst holding true to the traditional principles of quality engineering. Due to the compact design ESPA booster sets offer a small footprint in relation to performance. Installation is straightforward, with site work usually limited to connecting site pipe work and the provision of a suitable electrical supply.

Features

• Stainless steel suction and discharge manifolds AISI 304.
• Steel chassis finished in black epoxy coating.

ESPA In-Line inverter advantages

An innovative system that can be used with a variation of pump types including multistage and single stage. Saves energy, silent running, compact, and can extend the life of the pump. Designed to vary the frequency (Hz) of the pump in order to keep the hydraulic system at a constant pressure. Interface is user friendly, allowing easy use to calibrate pressure set points, view error messages, and setting. Works directly on the hydraulic manifold and installed on the discharge pipeline of the booster set.

The most efficient system for adjusting a pumps hydraulic performance to the pressure and flow requirements of supplying water is through the use of variable-speed technology. In the case of supplying water to a building that requires a constant pressure regardless of the water flow requested, with a variable-speed system, in addition to improved efficiency, a high-quality, oscillation-free service is obtained, guaranteeing greater durability of the equipment and the installation.

The ESD unit receives a proportional signal from a pressure transducer fitted on the discharge pipeline. The ESD processes this signal and regulates the motor speed in order to keep the pressure constant at the established level, regardless of the variations in flow demand.

With this pump set the pumps operation can be adapted to the different flow demands, constantly setting the consumption that is strictly necessary for the demand at any given moment. The energy consumption will be proportional to the water consumption. In comparison to the same system running at a fixed speed, this translates directly into energy savings.

Operating modes

The ESD has a backlit display and a 5-button keypad for displaying the user parameters. The installer can easily regulate and modify the basic operational parameters through the same interface. It also includes a reset option to recover the default factory parameters.

Adjustable operating parameters

• Language: options ES, EN, DE, IT, FR.
• Operation: AUTOMATIC MANUAL
• Set pressure: set point.
• Differential pressure: hysteresis or difference in the set pressure that marks the start-up of the pump.
• Maximum motor intensity: to regulate motor protection.
• Pump sleep frequency: sleep frequency; this can be set manually or automatically.

ESD has a system for automatically calculating the pumps sleep frequency on the basis of the specific characteristics of each installation and the set pressure point.
