WHEN PUMP PROBLEMS BECOME OPERATING PROBLEMS

A pump issue rarely stays at the pump.

With aggressive, corrosive or hazardous fluids, a leak, unexpected shutdown or unresolved requirement can affect people, production, the environment and product quality.

Incomplete application data can turn a technical selection question into a daily concern for operations, maintenance, production, HSE and quality teams.

Leakage and exposure concerns

If an aggressive or hazardous fluid escapes the system, safe access, environmental containment and product integrity can all become immediate concerns.

Unplanned production pressure

Cavitation, dry running, material mismatch or an unsuitable pump concept can damage equipment and bring a line or process to a stop.

Recurring maintenance workload

Seal wear, repeated intervention and uncertain spare-parts needs consume maintenance capacity and make reliable operation harder to plan.

Compliance and approval uncertainty

Unclear ATEX, FDA, TA Luft, material or documentation requirements can complicate internal approvals and the preparation of HSE, quality or audit reviews.

The question is not only whether a pump can move the fluid. It is whether people, process and equipment can rely on the complete solution.

WHAT YOU WILL LEARN

Turn critical application data into a structured pump pre-check.

The guide brings seven connected selection factors into one practical framework—so you can organise what is known, identify what is missing and prepare a more useful technical discussion.

Find the gaps

Identify missing details about the fluid, operating point, materials and installation before they shape the selection.

Connect the decisions

See how fluid properties, temperature, pressure, pumping principle and installation conditions influence one another.

Prepare the next step

Use the practical checklist to structure a request for a new installation, replacement or OEM application.

FROM PROCESS REQUIREMENTS TO PUMP SOLUTION

The right solution starts with three connected decisions.

No single pump principle, material or configuration fits every critical-fluid application. MARCH PUMPEN considers these dimensions together before a solution is assessed.

1. Pumping principle

Transfer, circulation, dosing, duty point and fluid behaviour determine which principle should be evaluated.

2. Material combination

The fluid, concentration, temperature and every wetted component must be considered as one material system.

3. Configuration and integration

Installation, connections, documentation, safety and OEM requirements shape the configuration to be reviewed.

Application data first. Pump concept second.

Each combination requires an application-specific technical review.

FOCUSED SOLUTIONS FOR CRITICAL FLUIDS

Different duties call for different magnetically driven pump principles.

MARCH PUMPEN can evaluate several magnetically driven pump concepts and material options for demanding fluid-handling applications. The relevant choice depends on the actual process—not on one catalogue value.

Chemical centrifugal pumps

A centrifugal principle to consider for suitable transfer, circulation and recirculation duties.

Chemical standard pumps

Standardised centrifugal pump designs to consider for suitable industrial process duties and integration requirements.

TEF-MAG® gear pumps

A positive-displacement principle to evaluate where small flow rates, higher differential pressures or controlled delivery are relevant.

VANE-MAG® sliding-vane pumps

A rotary positive-displacement principle to evaluate for suitable low-viscosity fluids, small flow rates and higher differential-pressure duties.

Material and configuration options

Depending on the application, different material options and customer-specific configurations can be included in the assessment.

This overview is not a product recommendation. Suitability, materials and operating limits must be reviewed for the specific application.

FROM PROCESS DATA TO TECHNICAL REVIEW

Move from catalogue comparison to an application-specific assessment.

At MARCH PUMPEN, technical consultation and individual pump sizing bring together fluid, duty point, materials, installation and integration requirements.

The aim is to identify which pump principles, material options and configurations are worth evaluating for the specific application.

1. Collect the application data

Capture the available fluid, operating and installation information.

2. Clarify gaps and constraints

Identify missing data, process risks and application-specific requirements.

3. Evaluate solution options

Assess which pumping principles, material options and configurations should be considered.

4. Review technical feasibility

Examine the selected options against the complete application before a recommendation is made.

Each application must be reviewed individually. This process does not replace material approval, compliance verification or detailed technical sizing.

ALREADY WORKING ON A SPECIFIC APPLICATION?

Request a technical feasibility review.

If you are planning a new installation, replacing an existing pump, changing the process or integrating a pump into an OEM system, send us the information currently available. The MARCH PUMPEN team can clarify which additional data is required for a technical assessment.

Helpful information to include

  • Fluid, composition and concentration
  • Required flow rate and differential pressure or head
  • Temperature, system pressure and operating mode
  • Installation conditions and current challenge
