We are your competent partnerfor solving your technical agita-ting problems.
The development of HOESCHagitators was started in 1937.Since that time we have established ourselves as one of the leading manufacturerson the international market.
Our process engineers have anextensive know-how and many
years of experience in nume-rous fields of application. We manufacture a completerange of agitators for a largenumber of mixing processes. A plurality of applications ispossible, e.g. in chemical, primary, food and beverageindustry, in hydrometallurgy, in coal cleaning and ore dres-sing plants, in domestic sewageand industrial waste water treatment plants, in paper
and cellulose mills, in environ-mental technology - especiallyin flue gas desulphurisationplants and garbage incinerationstations. Our success is based on themodern and perfected compu-ter-aided design of our agita-tors and on the performance of agitating trials in our mecha-nical engineering laboratory.

Agitating Elements
For different operating conditi-ons in the individual fields ofindustry, tank agitators (typeRT) with V-belt drive are available. Special designs with gearmotor and flexible coupling.

element, speed, sealing anddrive power are made accor-ding to the operating conditi-ons.
The agitator lantern is made of special cast iron (or of wel-ded steel) and has a hingedmotor plate. The solid shaftsare guided in two large antifric-
tion bearings.The installed single or double-acting mechanical seal has abuilt-in antifriction bearing forthe shaft. The second anti-friction bearing is located in a screwable bearing housing,near the upper bearing lantern,so it is best located near the V-belt drive.
Standard Programme Agitators, type RT
Dimensioning of tank agitatorsfor lateral installation is basedon our basic knowledgethanks to extensive tests andsupplies already since 1962 for crude oil, phosphoric acidplants with gypsum, titaniumdioxide plants, washing agentsas well as water glass, paints and varnishes, absorber discharges and residual dis-charges in flue gas desulphuri-sation, sewage, etc.

Agitators, standard sizes HSR 40 to HSR 125
This advanced line of compact HSR agitators withone-piece lantern meets the high requirementsmade on industrial agitators in every respect.
The bearing lantern is equipped with a doubleantifriction bearing system to optimize shaft gui-ding. Different shaft diameters according to DIN.
Thanks to this special construction different typesof sealings and drives can be used. HSR agitators are suited for demanding agitatingtasks in all branches of industry.

Agitators, type R / Large-size Agitators, type RS
HOESCH Agitators, type R / RSare very robust and suitable forall tank sizes.
The most important componentparts are graded according to amodular system. Thanks tointerchangeability of supportsfor seal and coupling, numerouscombinations as to the bearinglantern are possible. An inter-mediate flange allows the use
against lubricant leakage andcontamination. The shaft isalways connected with thedrive unit by a flexible coupling.Very long shafts are made ofseveral parts, connected byflanged couplings, to facilitatetransport and assembly.

Technical data
Agitators, type HSR
HOESCH-Agitator used in the zinc industry.
Agitators, type RFG
DIN Agitators with quick change attachment for simpleand quick exchange of the mechanical seal. Standard sizes RFG 3 – RFG 6 Shaft ø from 80 to 200 mm
HOESCH Agitators, type RFG,complete the range with well-proved standard seriesHSR, R and RS. On the photoyou see an advanced unitwhere the mechanical seal can be laterally removed.
Thus, disassembly of the gearlantern is not necessary. Theagitator lantern and the tankkeep connected.
After removal of the inter-mediate shaft and couplinghalf, the complete mechanicalseal with integrated antifrictionbearing can be removed bymeans of a lifting device. Weespecially point to the lowheight of the agitator drive.Thus, no additional height is
required for disassembly of the sealing.
The parts are easily accessible,since wide lantern openingsfacilitate disassembly. A two-part support plate below thebase plate supports the wholeagitator shaft.
Upon request, this series can be ordered with hydraulic liftingdevice.
