ESPA Prisma Horizontal Multi-Stage Pump
Multi-stage, integral, centrifugal, horizontal electric pumps for pressurising homes, low-scale irrigation systems and clean-water pumping applications that require a sturdy, compact pump.
Specially recommended for drinking-water applications.
Outstanding features include extremely quiet operation and self-suction capacity of up to 2 m, which is considerably increased with the installation of a foot valve.
Their reliability is added to their ability to work under many different conditions, and they are remarkable for their compatibility, including an ESD variable speed control module for automating their operation according to criteria of energy savings and installation efficiency. It is especially recommended for pressurisation at constant pressure.
