Pump and equipment selection for JESSBERGER systems

Request a pump assembly, flow meter or filling configuration for a JESSBERGER system. Define the liquid, duty point and installation; identify replacement components by model and drawing.

Drum pumps, pump tubes and drives

A drum pump combines a drive with an immersion tube assembly. Tube material, length and identification help specify a replacement coupling, rotor or complete tube.

PP, PVDF, aluminium or stainless steel tube
Electric or air-operated drive
Parts identified against the tube assembly drawing

JP-700 eccentric screw pumps

JP-700 pumps address viscous media that can still flow. Pumping depends on the geometry and clearance between the rotating rotor and stationary stator.

Vertical and horizontal arrangements
Rotor and stator selected as a matched working pair
Specify viscosity at the operating temperature

JP-800 and JP-810 air-operated diaphragm pumps

These double-diaphragm pumps use compressed air. The JP-810 programme includes FOOD and ACCURATE AC versions; AC is designed for external control in dosing applications.

Air supply adjusts delivery and head
Diaphragm material matched to the handled liquid
Provide the complete JP-800 or JP-810 designation

JP-850, JP-830 and JP-860 centrifugal pumps

JP-850 uses a horizontal arrangement, JP-830 is a vertical immersion pump and JP-860 uses a magnetic coupling. Each construction calls for its own component selection.

JP-850: mechanical seal identification
JP-830: shaft, bushes and coupling
JP-860: magnetic drive, casing and bearing parts

Flow meters and batch control

The programme includes turbine and oval-gear meters. Options include a pulse output or a preset volume function for controlling a pump or valve.

Measurement principle selected for the liquid
Check connections and flow direction
Match the output signal to the control system

Filling equipment and accessories

The small filling plant is designed around drum pumps and can be combined with a weighing scale. Container format, batch size and liquid behaviour guide the configuration.

Transfer from drums and containers
Hose, dispensing nozzle and adaptor selected together
Specify target batch mass for weight-based filling

Define the transfer duty before selecting a pump

Start with the operation: emptying a drum, transferring from a container, circulating a liquid or dispensing a measured batch. The required flow and head are only part of the specification. Installation position, starting method and the way the operator stops the liquid also matter.

For a complete assembly, describe the equipment already available on the production station.

Attach a simple sketch from the source container to the receiving vessel. Mark the elevation, hose length, internal diameter and installed valves. Add photographs of the connections and available working space.

A clear sketch makes it easier to compare a proposed pump configuration with the actual installation and to identify the accessories that belong in the supply scope.

Liquid properties and wetted materials

State the liquid name, concentration, operating temperature and viscosity at that temperature. Distinguish storage conditions from transfer conditions, particularly when heating or cooling changes the behaviour of the product.

A safety data sheet and the cleaning procedure help describe chemical exposure. Mention particles, fibres, deposits and any tendency to crystallise during a pause.

Drum pump tubes are offered in PP, PVDF, aluminium and stainless steel. Evaluate the tube material together with seals, bearings, hose and dispensing fittings. Cleaning agents are part of the exposure conditions as well.

For an existing pump, record its full material designation rather than relying on the visible colour of the tube or on the material of the outer casing alone.

Container dimensions and immersion length

Measure the usable immersion depth, neck height and opening diameter of the drum or container. Show how the pump is supported and where the discharge hose runs.

Compare dimensions using the same reference points: overall height including a motor handle and the effective immersion length describe different things. A photograph with a scale is useful for identifying an existing assembly.

When requesting a replacement tube, include its marking, material, diameter, discharge connection and the drive that will remain in service. Photograph both sides of the coupling. If a new container will be used, include its dimensions too.

Consider the space needed to withdraw the tube, disconnect the hose and carry out cleaning without rearranging the surrounding equipment.

Drive selection and available utilities

For an electric drive, copy the voltage, frequency, power and version marking from the nameplate. Include photographs of the switch, cable entry and connection to the pump tube. State whether the request covers a complete pump or a drive to be fitted to an existing tube.

Matching power ratings alone do not describe the mechanical connection or the mounting arrangement.

For an air motor or diaphragm pump, describe the air conditions at the equipment, the supply pipe and the available air preparation. Record the duty cycle, typical running periods, pauses and control method. Include the liquid properties and any hazardous-area requirements in the same specification.

This gives the selection process a defined operating context instead of an isolated motor description.

JP-700 working pair and viscous product handling

In an eccentric screw pump, the rotor and stator form the working pair. Their geometry and clearance affect pumping. For a new assembly, state viscosity, temperature, required delivery and line resistance.

Also describe what happens to the product during a stop: it may cool, settle or thicken inside the pipe. These observations help define the operating duty and the requested configuration.

For replacement parts, provide the pump identification, drawing and photographs of the removed rotor or stator. Mark measuring points and units on a sketch. Describe the observed wear and specify whether the request covers one component, a working pair or an assembled pump section.

If a replacement version has already been fitted, identify that installed version alongside the original documentation.

Diaphragm pumps and external dosing control

For JP-800 or JP-810 equipment, retain the complete type designation and material code. A diaphragm request needs the fixing arrangement as well as the visible diameter. For valve components, show the ball, seat and sealing elements or mark their positions on the relevant assembly drawing.

Include the mounting position and the conditions on the suction side.

Describe the actual symptom separately from the requested part: failure to start, irregular cycling, reduced delivery or air leakage. Add the operating air pressure and the maintenance history relevant to the request. If the task involves dosing, describe the external controller and required signal.

JP-810 AC is intended for external control, so its configuration should be identified explicitly in the equipment specification.

Centrifugal arrangements and suction conditions

JP-850, JP-830 and JP-860 use different layouts and drive arrangements. Preserve the complete model designation and include a general installation photograph. For a complete replacement pump, define the operating flow and head, liquid level and pump position.

For a spare component, mark the position on the drawing belonging to that particular pump version.

The manufacturer warns that dry running or air bubbles can damage a mechanical seal in the horizontal pump arrangement. A seal request should therefore include a description of filling and start-up conditions. For an immersion assembly, include depth and mounting details.

For a magnetic-drive pump, identify the internal assembly. These descriptions help keep component selection tied to the actual construction in service.

Flow measurement, filling and batch definition

Select a flow meter in the context of the handled liquid and operating range. The programme includes turbine and oval-gear measuring principles. State the measurement unit, connection type and purpose of the output.

If the signal controls a valve or pump, attach the controller description and connection diagram. Distinguish a display-only application from a batch-control application.

For filling equipment, specify the batch size, receiving container and the sequence used when changing containers. Volume measurement through a meter and mass measurement using a scale are different requirements. List the pump, hose, dispensing nozzle, adaptor and control elements separately.

This makes it easier to compare the proposed package with the components already available at the station.

Prepare an identifiable equipment and parts request

Provide a readable nameplate photograph, a general pump view and a close-up of the requested component. Keep letters, numbers and suffixes in the identification. If a manual is available, include its title page and the drawing containing the selected position.

That combination connects the requested component to a particular equipment version rather than to a generic pump family.

For an unmarked part, add a dimensioned sketch and a photograph of its mounting location. Specify quantities and the desired assembly scope. Keep the drive, pump tube, hose and dispensing accessories on separate lines when their scope differs.

Review the resulting specification for identification, material, quantity and included items, then retain it with the maintenance records for the installed equipment.
