1. Product introduction

Grundfos Dosing Skid Systems (DSS) are designed to feed liquid chemicals from a supply source (usually tank or drum) to an injection point.

Systems typically include:

• pre-piped pumps

• fittings

• other components (depending on the system) i.e. strainers, calibration columns, back pressure valves, pressure gauges, pulsation dampeners, pressure relief valves.

Grundfos Dosing Skid Systems (DSS) can range from pre-engineered, standard one- and two-pump systems on polypropylene or stainless steel bases, to custom systems with multiple pumps and tanks all piped on a common skid with complete controls.

Dosing Skid Systems (DSS) are available for all models of Grundfos metering pumps: hydraulically actuated and mechanically actuated pumps including Digital Dosing pumps with stepper motor technology offering up to 3000:1 flow turndown.

Features and benefitsGrundfos Dosing Skid Systems offer critical benefits:

• Faster and easier onsite installation in comparison with the purchase of individual components that must be separately piped, installed, wired and tested.

• Each system is delivered as a complete package so many installations may be as simple as connecting the piping and electrical.

• System designs can cover a wide range of capabilities and materials to suit most applications and environments.

• Systems can operate with manual control or can be provided with automation options to improve process control, efficiency and reliability.

• System pumps, piping and control panels are factory inspected and tested prior to shipment.

2) The maximum dosing flow of HV type pumps is reduced by up to 10%.

The maximum capacity is measured at maximum pump back pressure.

The pump can be operated in the range of 0.125% to 100% of the maximum dosing capacity.

6. Further documentation

WebCAPS

WebCAPS is a Web-based Computer Aided Product Selection program available on www.grundfos.com.

WebCAPS contains detailed information on more than 185,000 Grundfos products in more than 20 languages.

In WebCAPS, all information is divided into 6 sections:

• Catalog

• Literature

• Service

• Sizing

• Replacement

• CAD drawings.

Catalog

This section is based on fields of application and pump types, and contains • technical data• curves (QH, Eta, P1, P2, etc) which can be adapted to the

density and viscosity of the pumped liquid and show thenumber of pumps in operation

• product photos• dimensional drawings• wiring diagrams• quotation texts, etc.

Literature

In this section you can access all the latest documents of a given pump, such as• product guides• installation and operating instructions• service documentation, such as Service kit catalog

and Service kit instructions• quick guides• product brochures, etc.

Service

This section contains an easy-to-use interactive service catalog. Here you can find and identify service parts of both existing anddiscontinued Grundfos pumps.Furthermore, this section contains service videos showing you how to replace service parts.

WinCAPS

Fig. 8 WinCAPS CD-ROM

WinCAPS is a Windows-based Computer Aided Product Selection program containing detailedinformation on more than 185,000 Grundfos products in more than 20 languages.

The program contains the same features and functions as WebCAPS, but is an ideal solution if no Internet connection is available.

WinCAPS is available on CD-ROM and updated once a year.

Sizing

This section is based on different fields of application and installation examples, and gives easy step-by-step instructions in how to• select the most suitable and efficient pump for your installation• carry out advanced calculations based on energy consumption,

payback periods, load profiles, life cycle costs, etc.• analyze your selected pump via the built-in life cycle cost tool• determine the flow velocity in wastewater applications, etc.

Replacement

In this section you find a guide to selecting and comparingreplacement data of an installed pump in order to replace the pump with a more efficient Grundfos pump. The section contains replacement data of a wide range of pumps produced by other manufacturers than Grundfos.

Based on an easy step-by-step guide, you can compare Grundfos pumps with the one you have installed on your site. When you have specified the installed pump, the guide will suggest a number of Grundfos pumps which can improve both comfort and efficiency.

CAD drawings

In this section it is possible to download 2-dimensional (2D) and3-dimensional (3D) CAD drawings of most Grundfos pumps.

These formats are available in WebCAPS:

2-dimensional drawings:• .dxf, wireframe drawings• .dwg, wireframe drawings.

3-dimensional drawings:• .dwg, wireframe drawings (without surfaces)• .stp, solid drawings (with surfaces)• .eprt, E-drawings.
