PumpDrive: flexible speed control for maximum efficiency

PumpDrive is the latest generation of KSB’s variable speed systems. It ensures demand-driven pump operation and, hence, maximum energy savings.

Saving energy with PumpDrive? PumpDrive continuously matches pump speed to system requirements. This ensures energy-efficient and reliable operation of the pumps. Speed control of pumps is highly recommended, especially for systems with fluctuating demand. Demand-driven operation through speed control saves up to 60 percent on energy and increases both the efficiency and the availability of the pump.

PumpDrive lowers energy costs and reduces the pump’s life cycle costs by controlling the pump input power. Maximum energy savings can be realised by combining PumpDrive with the PumpMeter pump monitoring unit and KSB SuPremE®, the world’s most efficient magnet-less pump motor.

Sample calculation

Etanorm PumpDrive 32-200/552. A demand-based reduction in the flow rate by just 30 % translates into savings of € 1,712/8,000 operating hours (at 12 cents/kWh).

Einsparpotenzial mit PumpDrive

Safe and reliable pump operation

Reliable pump operation requires continuous monitoring of the installation. The pumps' operating status has to be checked frequently. PumpDrive therefore continuously records and processes values, readings and data to monitor the permissible operating range at all times and ensure system availability.

Special features of PumpDrive:

Characteristic curve control and flow rate estimation

PumpDrive monitors the pump’s characteristic curves and estimates the current operating point on the basis of the motor input power and the current speed. This, in turn, allows PumpDrive to detect operation outside the permissible range such as extremely low flow, dry running or overload conditions. Predefined settings allow messages to be output in the case of extremely low flow or overload conditions. Depending on the settings, the pump set is stopped, which protects pumps against failures and damage resulting from operation in an impermissible range.
Continuous flow rate estimation is another essential PumpDrive feature. The flow rate is estimated on the basis of power measurement and the characteristic curve function. The estimated flow rate provides essential information for dynamic pressure compensation and other important functions.

Pressure boosting functions package: constant system pressure thanks to PumpDrive

Constant system pressure plays an important part in ensuring the availability and efficiency of pressure boosting pumps. The new PumpDrive integrates special functions that cater in particular to the special requirements in pressure boosting applications: the pipe filling mode and the sleep mode.

Redundancy by dual pump management

Thanks to integrated dual pump management, the predefined setpoint for the system is ensured at all times by way of two identical pumps. A distinction is made between two operating modes.

  • The setpoint is achieved with one pump operating at rated values. (2 x 100 %)
  • The system's rated operating point is achieved with both pumps operating at rated values. (2 x 50 %)

Flexibility in diverse applications

For every requirement and every application: With a broad range of ratings from 0.37 kW up to 110 kW (up to 1.4 MW available on request), PumpDrive provides for top levels of operating reliability and optimum efficiency in industrial applications much in the same way that the Eco design caters to building services applications.
PumpDrive's flexibility is also reflected by its mounting options: the speed control system can be mounted to the wall, on the motor or in a control cabinet. The three mounting options allow PumpDrive to be positioned where you need it, meeting individual requirements and conditions on site.

Motor-mounted model

PumpDrive can be mounted directly on the motor PumpDrive can be mounted directly on the motor

As the new PumpDrive has been perfectly matched to the motors of KSB pumps, it can be mounted directly on motors up to ratings of 55 kW. Benefit of motor mounting: retrofits eliminate the need for installation space in the control cabinet and the search for a suitable section of wall.

Wall-mounted model

…or on the wall. …or on the wall.

Should the space in the control cabinet be restricted or motor mounting not be possible, wall mounting is an ideal alternative. Wall mounting allows the pump and PumpDrive to be arranged in the immediate vicinity of each other.

Cabinet-mounted model

As a third option, it can also be mounted in a control cabinet. As a third option, it can also be mounted in a control cabinet.

If the pump is installed in a demanding environment, PumpDrive can be mounted in a control cabinet. Cabinet-mounted PumpDrives can be used up to ratings of 1.4 MW.

Easy to install, operate and maintain

  • Pump and PumpDrive parameters are factory-set.
  • Easy-to-fit M12 cable connector for joining PumpMeter and PumpDrive
  • Optionally integrated master switch for disconnection of the entire pump set from the power supply and protection against unintentional start-up

Functional and convenient: the My PumpDrive app

PumpDrive can be controlled via a smartphone display. KSB's handy My PumpDrive app is available free of charge in English, French and German from the iTunes Store.

  • Operation and monitoring: Access to key parameters, display of alerts and warnings, presentation of trends and graphical display of current parameters
  • Commissioning wizard for the three main applications: open-loop control, discharge pressure control, differential pressure control
  • Managing data records: Send parameter sets from your smartphone to PumpDrive, from PumpDrive to your smartphone, or per e-mail to your PC.

PumpDrive App

Variety for maximum efficiency

The new PumpDrive is available in two configurations, each of which offers a different level of functionality. One of them is the fully equipped model for flexible applications and the exacting demands in industry. The second model, the Eco version, includes the full range of basic functions and is ideal for use in building services applications. With its different models, KSB supplies pump variable speed systems matched to the specific requirements.
