CKE2-Multi-VS 2 pumps

Summary

Product identification

The ESPA CKE2 MULTI VS series comprises variable speed pressurization booster sets. The product line includes both twin pump booster sets and single-phase single pump sets.

Applications

ESPA CKE inverter booster sets are designed to provide an efficient solution for water boosting applications where existing supplies are unreliable or insufficient to meet building or application demands.

Operation principle

These are fully automatic variable speed booster sets, controlled by an ESPA ESD Speedrive (Variable Frequency Driver) to provide water supply at constant pressure.

• Twin pump booster sets can operate in duty-assist or duty stand-by configurations.
• All pumps operate at variable speed.
• The system adapts motor speed to water demand, ensuring requested pressure at any flow.
• Pressure is controlled by a transducer on the discharge manifold, allowing the ESPA Speedrive to regulate pump speed and save energy by adapting power consumption to the water demand.

Features

• Stainless steel suction and discharge manifolds AISI 304.
• Chassis finished in black epoxy coating.
• WRAS approved nickel plated brass ball valves on each pump for individual isolation.
• WRAS check valves on each pump.
• Anti-vibration mounts as standard.
• 8, 12, or 24 liter expansion vessel (WRAS approved), depending on pump size.
• Control panel with MCB’s.
• FVC (Free volt contacts) for external alarm control.
• Full documentation provided with each booster set.

ESPA ESD advantages

The ESPA ESD system is an innovative solution compatible with various pump types, including multistage vertical or horizontal pumps. It offers:

• Energy savings up to 50%.
• Silent running.
• Compact design.
• Extended pump life cycle.

Hydraulic performance

Hydraulic performance areas for CKE1M and CKE1 models are presented graphically in the official PDF, showing relationships between flow (Q in l/min, m³/h, U.S. g.p.m., Imp g.p.m.) and head (H in m, ft, kPa). See the official PDF for exact tabulated values and performance curves.
