Delivering maximum benefitto our customers is our keyprinciple. To this end, we areprepared to abandon conven-tional approaches and explorenew avenues. At the sametime, we make sure not toneglect traditional values

such as reliability, quality, trust and sharing experience.This philosophy is deeply engrained in the awareness of ourstaff and reflected in our work strategies and productionmethods.

Our market success is founded on in-company research anddevelopment in conjunction with our knowhow acquiredfrom decades of experience.

Information exchange and efficient communication with ourcustomers are at the heart of everything we do. No wonderthat ever more plant operators in the metal winning andprocessing industries are opting for our pumps.

As an owner-controlled medium-sized company, we arepursuing a long-term strategy. All our business decisions aredirected towards the principle of sustainability. For you andyour company, this means reliability and predictability.

Innovative products, decades of experience and a comprehensive service portfolio

are the ingredients of our formula for your success.

FlowStar®

MUNSCH GmbH is a highly specialized manufacturer of non-metallic pumps. Customers

around the globe bank on our pumps whenever it comes to ensuring maximum operating

reliability in abrasive and aggressive service conditions.

� DesignWe design pumps to our customers' specifications

Our engineers develop pumps for your specific needs.Application engineers from industry and university resear-chers support the development process through to produc-tion maturity of the pump. Rising energy prices are posinga new challenge to our development teams: developinghigh-efficiency pumps is one of their answers. A numericallyoptimized hydraulic design is their contribution to energyeconomy.

Another challenge for our engineers is to provide you withpumps that do not only cover the standard performancecharacteristic range but offer at the same time ample pumphead reserves. In tackling this task, they always keep inmind the FlowStar® concept: operating reliability, robust-ness, ease of assembly, maximum hydraulic performanceand low life-cycle cost.

� ManufactureOur vertical integration makes for short responsetimes

We manufacture all plastic components in-house usinggranulate or semis as starting products. This makes us in-dependent of external manufacture so that we can respondfast and flexibly to customer needs. Bought-in cast iron orsilicon carbide components are standardized and kept onstock in large quantities.

In a single operation, the blanks are further processed tothe finished product on our state-of-the-art five-axis millingmachines. Each individual component produced is documen-ted in an electronic database so that the original compo-nent can be exactly reproduced even after years.

� AssemblyConsistent quality documentation ensures traceability

Following release by Quality Assurance, the individualpump components arrive at the assembly workbench just intime. Our assembly team assembles the pumps using thelatest methods and performs and documents the qualitytests/inspections at defined hold points on the basis of arigorous test/inspection schedule.

� TestingNo pump leaves our production site untested

Each pump is tested on our test bench. Only when thepump achieves the guaranteed operating point, will it bereleased for shipment. A test report is submitted for eachpump delivered.

� ServiceWe are at your service around the globe

MUNSCH chemical pumps operate in Europe and overseas.Thanks to our worldwide sales and service network you willfind a technician who is familiar with every detail of ourpumps in all industrialized countries. Our local sales andservice engineers will be available to you, whether forpump inspection and repair or for on-site advice.

Priming pot Made of plastics

Operating principle A priming pot filled with liquid is arranged between thepump and the suction pipe. During the startup phase, thepump draws the liquid from the priming pot therebycreating a vacuum in the priming pot.

The liquid in the tank to be emptied is under atmosphericpressure; vented system. Under the action of the pressuredifferential, the liquid is forced into the priming pot. As aresult, the suction line is vented and the pump can lift theliquid from a level well below the pump.

Technical specification - The effective volume of the priming pot must exceed the

filling volume of the suction line by a factor of 1.5 to 2.0.- Priming pots are available in volume sizes of 10 to 26 l.- Standard construction material of priming pots:

polypropylene (PP), other materials can be suppliedon request.

Horizontal pumps can be retrofitted with a priming pot toprovide self-priming capability. The priming pot is installedbetween the suction pipe and the pump.

Suction from a source located above the pump centreline

Suction from a source located below the pump centreline
