Applications

the Grundfos HS pumps are used in these main fields of application:

Commercial systems

• Air-conditioning and chilled water system

• Water condensing systems and cooling towers

• District heating plants and heating systems

Industrial systems

• Process cooling and chilled water systems

• Industrial heating systems

• Washdown and cleaning systems

Water distribution

• Public waterworks

• Non-potable water systems

Irrigation and agriculture

• Field irrigation (flooding)

• Sprinkler irrigation

PuMP dEScrIPtIon

• The pumps are non-self-priming, centrifugal volute

pumps with radial suction and radial discharge ports

and horizontal shaft.

• Suction and discharge flanges are PN 16 according to

EN 1092-2 (DIN2501).

• The pump is long-coupled with a totally enclosed fan-

cooled standard motor with main dimensions to IEc

and dIn standards and mounting designation B3

(IM 1001).

• The mechanical shaft seal has dimensions according

to En 12756.

• The rotating assembly is dynamically balanced

according to ISo 1940 class G6.3.

• Impellers are double suction providing long operating,

corrosion free life. Impellers are constructed in

ASTM B584 bronze and are hydraulically balanced.

• Grundfos HS pumps are available in three different

variants:

1. Pump with motor and base frame.

2. Bare shaft pump with base frame.

3. Bare shaft pump; ie pump without motor and without

base frame.

• The split-case construction enables removal and

dismantling of the internal pump parts, e.g. bearings,

wear rings, impeller and shaft seal, without disturbing

the motor and pipework.

• Replaceable case wear rings protect the pump casing

while reducing maintenance costs and maintaining

high operating efficiencies.

• Pump and motor are mounted on a common base

frame in the form of a welded, steel C-channel profile.

• Bronze shaft sleeves protect the shaft and help with

fixation of the impeller.

SELLING FEATURES

Pump casing

• Compensated double volute design virtually eliminates

radial forces caused by a hydraulic imbalance inherent

in pump volutes

• Double volute design extends seal and bearing life,

minimizing noise and vibration, and improving

operating efficiency – meaning less wear and lower

maintenance costs

Bearing Housing

• Grundfos superior design combines seal and bearing

chambers to allow inspection without removing the top

half of the pump casing – saving time, reducing the use

of lifting equipment, and decreasing the safety risk

• Compact, robust housing construction has a 360-degree

machined fit and limits shaft deflection and optimizes

alignment

Impeller

• Extended vanes and enlarged eye contribute to a

reduction in vibration and noise

Coupling

• Grundfos specified grid coupling designed to meet the

pump torque requirements provides long service life

and reduced maintenance costs

10 Ways to Kill Your HS Pump

1. Overwork it

Work the pump continuously at higher capacities, flows, heads, or speeds than originally specified.

2. Starve it

Never grease or oil the pump.

3. Choke it

• Lower the water level in the sump.

• Let the suction strainer clog and never clean it.

• Let the temperature of fluid rise without raising

the suction pressure.

4. Fry it operate at shutoff for a long time with the bypass line closed tight will convert your power to heat.

5. Poison it

Change the pumped fluid without checking with the manufacturer (for example adding chemicals).

6. Stab it

Remove the suction strainers which will introduce grit, sand, and scale into the fluid.

7. Break its limbs

Impose heavy piping loads on the suction and discharge nozzle, either through initial misalignment or through thermal expansion.

8. Shake it

Don’t align at installation or install on a flimsy foundation.

9. Drown it

For a packed pump with a drain for the gland leakage:

• Plug the drain with a cigarette butt, gum or paper.

• Remove the water shield.

• Line up the splits on the packing rings.

10. Neglect check-ups

• Ignore the manufacturer’s recommendations for

“check-ups”

• Don’t check packing, gaskets, o-rings, or

other small parts.

• Don’t ever repaint it, or lubricate the coupling,

if required.

• Don’t check vibration.
