Constant pressure system
Speedrive Espa VFD for pumps

Constant pressure inverter system for pumps with three-phase motors.

Nomenclature: Speedrive

Company: Espa
Function: constant pressure management
Available versions:single-phase/three-phase & three-phase/three-phase
Technology: Adjustable-frequency drive
Heat dissipation: forced air by the motor
Adjustment range: from 0.3Bar to 10Bar
Max power: 3Kw - 9A (SPEEDRIVE T3)
Installation: on the motor terminal board - or on the wall (request kit)
Transducer: 10Bar (not included)

Expansion vessel/tank: recommended (min.20% max flow of the pump)

Why should you add the expansion vassel to the frequency inverter drive system?

The basic plant does not require the use of a compensation tank/vassel. But if you want to maximize the energy consumption and the duration of the electric pump, it's necessary to add a tank. In fact, by using a water tank, the continuous and repeated starts of the electric pump (due to small withdrawals and/or water leaks in the water system) are avoided; Decreasing the start/stop of the electric pump:

1) Decreases energy consumption;

2) Extends the life of the electric pump.

Attention: the power value (maximum power load) is indicative. For a correct match with the electric pump, it is essential to verify that the amps absorbed by the electric pump do not exceed the amps allowed by the inverter.

ESPA SPEEDRIVE VARIABLE FREQUENCY DRIVE

The Speedrive series variable frequency drives represent an advancement in speed controllers for pumping systems, improving important aspects like functionality, with more user-friendly programming and more reliable systems.

VFD inverter system are designed to operate pumps with three-phase motors at constant pressure.
The series includes the M2 230Vac single-phase input voltage and the T2 and T3 models of three-phase/three-phase type;
Espa Speedrive must be coupled & connected directly to the motor control board. Motor air induced cooling.

10 BAR transducer

The newly developed Speedrive Espa inverters are able to work in groups of up to 4 pumps with VFD in communication;
They provide pumping systems with better hydraulic features, constant stable pressure, smooth and silent operation, extended lifespan of pumps, savings in electricity consumption resulting in cost reductions over the life cycle of the installation.
