Description

THE SMART DIGITAL RANGE
Accurate digital diaphragm dosing pumps

A solution for all dosing applications

Whether your job is to ensure safe pool water or to add coagulants in complex industrial manufacturing processes, you know that dosing pumps are an important part of the process. You probably also have some strict requirements that need to be met: Chemicals must be dosed accurately so you can avoid overdosing, spillage, and soaring costs. Pumps must be tough and reliable, but still user-friendly, so you get dependable and safe processes, especially when hazardous chemicals are involved. Pumps must be energy-efficient, and must require minimal service and maintenance, so you can control operating costs. And if you need to handle many different installation sites, perhaps even in many different countries, you need pumps that are flexible and easy to configure.

Fulfilling all requirements

The SMART Digital range of diaphragm dosing pumps from Grundfos gives you all of this, and more. Covering flow rates up to 200 litres an hour, and output pressure ratings up to 16 bar, the SMART Digital range delivers reliable, safe, and costeffective dosing in any application across a wide selection of businesses, with industry-leading user friendliness and flexibility. And the advanced monitoring and self-analysis features offered by several control variants provide intelligent process control that looks beyond the pump and keeps an eye on the entire system for you.

A complete package

The SMART Digital range comes with a wide selection of accessories such as installation kits, signal cables, and dosing tanks that make it even easier to customise the pumps to any application. SMART Digital pumps have very long service and maintenance intervals, significantly lowering pump life-cycle cost and contributing to disruption-free, reliable dosing performance. And when service is needed, our tailor-made service kits ensure optimal service that keeps pumps running in top condition for years.

In short: The SMART Digital range offers a complete package of dosing solutions for any business. Including yours.


MAIN BENEFITS OF
THE SMART DIGITAL RANGE

Accurate

Stepper and permanent magnet synchronous motor technology with optional flow control features make it possible for the SMART Digital range to achieve market leading dosing accuracy. The SMART Digital DDA-FCM, for example, deviates less than one percent from the set point at flow rates from 50 ml/h and up.

 

Flexible

High turn-down ratio. Wide supply voltage range. Mounting plate. Adjustable control cube. These are just some of the features that make the SMART Digital range flexible enough for any application. Pumps can quickly be reconfigured and assigned for new tasks in response to changes in demand.

 

Safe and reliable

The unmatched accuracy of the SMART Digital pumps minimises spillage and contributes to safe operating procedures. Several control variants provide auto-deaeration, monitoring, and self-diagnosis features that improve installation safety and reliability.

 

User-friendly

From intuitive wheel and button interfaces to clear, backlit navigation menus available in well over 20 languages, SMART Digital pumps are very easy to set up and operate. With many control variants, calibration is not necessary, and you can trust the pump to do its job – or warn you in case of problems.

 

Cost-effective

Robust pump components such as the full-PTFE diaphragm provide thousands of hours of reliable operation before service is needed. Several control variants make external flow meters and pulsation dampeners unnecessary, and the great dosing accuracy and energy efficiency save chemicals and power.


SMART DIGITAL S
Extreme accuracy at low dosing volumes

At dosing volumes up to 30 l/h, the SMART Digital DDA, DDC, and DDE offer extreme dosing accuracy and several control and communication options. The compact pumps can easily be mounted on horizontal or vertical surfaces with the click-stop mounting plate.

DDA

The high-end DDA pump is designed as the perfect solution for complex and demanding applications. It handles degassing liquids without any problems thanks to its auto-deaeration feature – also during pump standby. The FC control variant offers FlowControl with selective fault diagnosis as well as built-in pressure monitoring, and the FCM control variant additionally offers integrated flow measurement and the Auto- FlowAdapt feature which allows the pump to adjust pump speed to actual conditions. The pump offers batch modes (timer or pulse based) and can be delivered with an optional E-box for Profibus DP integration.

 

DDC

The DDC pump is the optimum solution for many common applications. The pump offers manual and pulse control operation modes, and the built-in Slow- Mode can be used to dose high-viscosity liquids. The easy-to-use interface with the click wheel makes setup and operation as easy as turning up your stereo. The AR control variant offers analogue control, relay settings for alarm, warning, stroke signal, and pump dosing, an input for analogue 0/4-20 mA control, and two output relays.

 

DDE

The DDE pump offers a cost-effective Digital Dosing™ solution with basic functions for simple applications. Only two pump variants cover the entire flow range. Setting dosing capacity from 0.1 to 100% is easy on the intuitive user interface. The PR and P control variants offer pulse control (1:n), and inputs for external stop, low level, and empty tank signals. The PR control variant also offers relay setting of alarm, warning, stroke signal, and pump dosing as well as two output relays.

TECHNICAL SPECIFICATIONS


SMART Digital DDA-FCM

SMART Digital DDA-FCM provide high accuracy, reliability, safety, user-friendliness, and flexibility. With the DDA-FCM the dosing process is monitored and, if necessary, appropriate errors are corrected. Control cube of the SMART Digital can be flexible adjusted to face left, right, or straight ahead.

– Accurate and smooth dosing
– Process Safety, overpressure, line burst, air bubbles, cavitation
– AutoFlowAdapt
– Modularity and Flexibility


SMART DIGITAL XL
Three model variants, Endless possibilities

For applications requiring accuracy at flows up to 200 l/h, the SMART Digital XL DDA and DDE units cover the entire range with only three pump models. The pumps offer many of the same control and communication options as the SMART Digital S dosing pumps but with greater flow performance. The pumps can easily be mounted on horizontal surfaces with the clickstop mounting plate.

The high flow performance of the SMART Digital XL pumps make them the ideal option for applications that require high flow and high accuracy, such as flocculant dosing. For other applications, such as polymer dosing in drinking water treatment, the combination of high flow rates and high pressure offered by the SMART Digital XL pumps (such as 120 l/h at 7 bar) delivers the results needed.

DDA

With CIU integration options and multiple built-in control and communication features, the DDA pump is the most advanced SMART Digital XL offering. Like the SMART Digital S DDA, it offers value-added features such as auto-deaeration and can be specified in control variants with FlowControl, built-in pressure monitoring and flow measurement, and AutoFlowAdapt. With accuracy that is unrivalled in this flow performance range, the DDA delivers safety, flexibility, and user friendliness for a wide range of applications.

 

DDE

Like the small SMART Digital DDE, the SMART Digital XL DDE offers cost-effective Digital Dosing™, but it meets more application requirements thanks to its larger flow range. The AR control variant offers value-added features such as pulse control in ml/pulse and an input for analogue 0/4-20 mA control. The B control variant delivers basic dosing features with manual speed control in an operator-friendly unit. When high flow performance at a competitive price is needed, the SMART Digital XL DDE is the answer.
