APPLICATION

CONSTRUCTION

Hygienic centrifugal pumps of the NHK and SHK range are used
within the food and beverage industry such as breweries and

Casing pressure:

dairies. Applications areas for these pumps include:

NHK 25:

max. 10 bar up to +130 °C

- Brewing (Mash, wort, beer)

NHK from 50:

max. 16 bar up to +130 °C

- Dairying (milk, cream, fats)

SHK:

max. 10 bar up to + 90 °C

- Filtration (Filtration, separation, mixing)
- Cleaning (Up & Downstream CIP)
- Filling (Beer, soft drinks, juices)
- Sterile and pure water

Flange location:
Axial suction, radially vertical discharge.

Connections:
Threaded connections to DIN 11851 or flanged.
Design
The single stage NHK is a hygienic volute-casing pump with open
impeller (for optimised pumping of shear sensitive media) rotating
on a robust shaft. The thick-walled stainless steel casing is fixed

Hydraulic:
Design code A for n = 1450 1/min
Design code B for n = 2900 1/min

by a sturdy quick-release clamp ring with sanitary grade O-ring
sealing. All process-wetted parts are constructed from electropolished AISI 316L stainless steel. Importantly, the volute casing
is rolled steel whilst the casing cover is forged in order to give a
heavy-duty construction. All other parts are made of AISI 304.
The SHK range is a single stage, self-priming, hygienic side
channel pump. All process-wetted parts are made of AISI 316L. All
other parts are made of AISI 304.
The NHK and SHK range are in accordance with food-grade
standards 3A1 with a surface roughness Ra ≤ 3,2 µm (other

Shaft sealing:
Shaft sealing can be either single or double mechanical seal.
Design code X0A: single mechanical seal, seal face materials
SiC/SiC, elastomer EPDM
Design code X0B: double mechanical seal, seal face materials
product side SiC/SiC, elastomer EPDM,
atmospheric side Cr-Steel/carbon, elastomer
EPDM

standards are optional). The Modular and compact design, the use
of standard motors and several options guarantee a reliable
performance within the food and beverage industry.
