A purpose-built range of variable frequency drives, designed to control and protect pumping systems based on changing pump speed.

From water supply for domestic, irrigation, liquid transfer and industrial applications, to heating and air conditioning, commercial building services, filtering pressurewashing, the VASCO range perfectly fits any new or existing application.

Vasco Unit

Vasco also provides motor protection and monitoring, such as:

Protection against overload and dry running
Integrated soft start & soft stop functions, extending the life of the system & reducing peak absorption
Indication of input current and supply voltage
Recording running hours and logins errors and alarms reported by the system
The Vasco can control a second or third pump at constant speed DOL (DOL: Direct On Line)
Connect to other VASCO units to get combined operation

VASCO units are extremely compact and will manage the operation of the pump to maintain a constant requirement (such as pressure, flow, temperature or other). The pumping system runs only at the speed necessary to meet user's requirements, ensuring energy savings and extending the life of the system.

The body is constructed entirely of aluminium, making VASCO, with its compact dimensions, extremely solid, lightweight and easily cooled, adding to the unit's versatility. The degree of protection, IP55, makes it possible to install VASCO virtually anywhere, including a humid and dusty environment. The liquid crystal illuminated display ensures VASCO is easy to operate and a buzzer provides an immediate indication of alarm.

Wall Kit

VASCO is cooled by an external cooling fan attached to the inverter radiator. A special metal bracket is supplied for the VASCO to be wall mounted.

Motor Kit

VASCO is cooled by the motor cooling fan. Motor kits consist of 4 special clamps to fix the VASCO to the motor fan cover.

Installing the Vasco is Simple, User Friendly & Consists of a Few Quick Steps

If the water demand changes frequently, it is advisable to share the load using a multiple pump group, resulting in greater reliability and efficiency.

Connect the VASCO to power supply
Connect the VASCO to pump
Connect the VASCO to the pressure sensor , located wherever in the piping you want to maintain the desired constant physical dimension
Set the VASCO to configure the pump to the system, and the required performance

1 VASCO + 1 or 2 DOL

A first way of splitting consists of installing one pump driven by the VASCO and 1 or 2 DOL pumps directly connected to the main power (Direct on Line) ; VASCO alternates the two DOL pumps (same working time) to even out pump wear.

1 to 8 VASCO in COMBO connection

A second way of splitting (named COMBO) consists of using several pumps in parallel (up to 8) each one driven by a VASCO unit. In this way efficiency and the reliability of the pump group is maximised. Vasco controls and protects each connected pump. Each VASCO controls and protects its pump and the operation is shared among all the connected pumps to average out pump wear; in case of failure, the remaining pumps will maintain the pumping operation.
