Multi-VS-ESD
PDF datasheet mirror for Multi-VS-ESD (ESPA Pumps). Verify with OEM before design.
Summary
Product identification
The Multi VS-ESD is a surface vertical variable speed pump featuring an integrated ESPA Speedrive (ESD) variable-frequency controller. This integration extends the hydraulic range for each model, ensuring efficient operation at various duty points beyond the restrictions of a fixed-speed pump curve. The ESD module can be adapted to three-phase motors in both new ESPA pumps and existing installations, improving system service quality and extending unit lifespan. This variable-speed system delivers constant pressure in varying demand systems and allows for the replacement of large accumulation vessels with smaller units.
Applications include:
- Water supply and pressure boosting for residential, commercial, or services buildings.
- Clean water transfer, water treatment, irrigation.
Mechanical / hydraulic
- Materials:
- Hydraulic components: Stainless steel AISI 304 or AISI 316 (version N).
- Mechanical seal: Silicon/carbon/EPDM.
- Equipment:
- Supplied with a standard pressure transducer (10, 16, or 25 bar).
- Counter flanges (optional extra).
Electrical
The ESPA inverter Speedrive has the following voltage ranges for disconnect and automatic reset:
- M2-M3 (1~230 V, model M):
- Low voltage disconnect: 180 V
- Automatic reset: 195 V
- High voltage disconnect: 270 V
- Automatic reset: 250 V
- T2-T3 T4 (3~400 V, model T):
- Low voltage disconnect: 310 V
- Automatic reset: 335 V
- High voltage disconnect: 485 V
- Automatic reset: 475 V
