Product introduction

DSS 1

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 benefits

Grundfos 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.
