Vasco is a purpose built family of variable speed drives, designed to control and protect pumping systems based on changing pump speed.

From water supply for domestic, irrigation, commercial and industrial applications, to heating and air conditioning, from filtering to pressure-washing, the VASCO range perfectly fits any new or existing application ensuring:

-energy and cost saving

simplified installation

longevity of pumping system

greater reliability


VASCO units are extremely compact and, connected to any pump on the market, will manage the operation of the pump to maintain a constant desired physical dimension (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.

Vasco also provides motor protection and monitoring , such as:

- protection against overload and dry running

- integrated soft start and soft stop functions, extending the life of the system and reducing peak absorption

- indication of input current and supply voltage

recording running hours and logging errors and alarms reported by the system

- Vasco can control a second or third pump at constant speed DOL (DOL: Direct On Line)

connect to other VASCOs to get combined operation

Body is constructed entirely of aluminum, 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 humid and dusty environments; the liquid crystal illuminated display ensures VASCO is easy to operate and a buzzer provides an immediate indication of alarm.

MacEwans Variable Speed Pressure Booster Sets

MacEwans Pumping Systems can supply constant pressure boosting systems controlled by Vasco variable speed pump controllers (1 to 8 pumps).

With Vasco variable speed drives it is possible to operate booster sets with one or more pumps (up to 8) controlled at constant pressure.

Vasco variable speed controllers can be mounted directly to the motor fan cover with a mounting kit; the strength of the connection kit allows the VASCO to be installed on horizontal pumps.

The screen display can be easily rotated for easy viewing

Motor mounting achieves compactness with savings in additional control panels and wiring.   Very good cooling of the inverter are are achieved and low electromagnetic emissions due to the reduced length of motor cable.

IP55 protection allows installation in humid and dusty environments.

If the VASCO variable speed drive cannot be installed on motor fan cover, it is possible to fix the VASCO variable speed drive to the wall with an optional kit and cooling fan feed by the VASCO.

IP 55 protection does not require installation of the VASCO variable speed drive into any additional control box so VASCO can be installed very near to the pump.
