Design options
Metal or polymer body; diaphragm, ball and seat materials. Compatibility is assessed against fluid composition and temperature.

Ship supply and marine products
We consolidate ship enquiries using IMPA codes, manufacturer articles and technical specifications. This sector covers marine equipment, consumables, ropes, shackles, clips, slings and Wilhelmsen products. We source the full IMPA Marine Stores Guide range to order; the published catalogue continues to grow. Availability and dispatch timing from supplier warehouses are confirmed for each enquiry.

Marine supply / Selection by task
Start with a requirement or a specification
Marine pumps, cleaning equipment, breathing-air compressors, shackles, clips, ropes and slings. Choose a family and describe the task; parameters are checked for the specific design.
Illustrations show examples of particular designs. The actual construction, materials and supply scope are confirmed in the offer.
Designs and supply scope
We select the pump together with its wetted parts and air-supply requirements. For replacement, start with a nameplate, connection photos and a fluid description.
Start with these details
- Fluid and service temperature
- Required flow and discharge conditions
- Available compressed air or pump nameplate
Start with the information you have. We will clarify the rest together.
Supply scope
Pump only, connection package or spare parts. Air preparation, hoses, valves and a pulsation dampener are included as specified.
Replacement and documents
When replacing equipment
Check duty point, suction line, connections and available air supply. Matching port size alone is insufficient to approve a replacement.
Spares and consumables
For diaphragms, balls, seats and the air section, record the exact model and part materials. List repair-kit contents so the same kit name does not conceal different scopes.
Documented requirements
Agreed performance, wetted materials, dimensional drawing, instructions and included accessories.
Questions before ordering
I only have a photo of the old pump. Where do I start?
Send a readable nameplate, overall and connection views, plus a short fluid description. We identify the missing information needed for an offer; a photo alone does not confirm performance.
Can I replace it with a pump of the same port size?
First compare delivery at the required head, suction conditions, materials and air demand. We then agree the design and differences; port size is only one parameter.

How we prepare engineering enquiries
Anonymised tasks from our procurement archive: technical preparation completed and matters still requiring confirmation.
Technical preparationPump spares: from a description to an exact partPrepared an enquiry tying each part to the model, serial configuration and drawing position.
Task
A spare-parts list contained ambiguous descriptions. Ordering by a translation alone could select a different assembly.
What we prepared
The enquiry requested identification against manufacturer production records, with an official description and order number for each item. Origin and part applicability were requested separately.
Status and next step
A specification was prepared for clarification and quotations. Part applicability still requires manufacturer confirmation; this example does not establish delivery.
Technical preparationReplacement of a hydraulic gear pumpPrepared comparison requirements for the original pump and a proposed alternative.
Task
A proposed alternative required configuration checks; a similar purpose or description was insufficient to approve replacement.
What we prepared
Requested comparison of displacement, rotation, shaft, flange, ports, operating limits and permissible fluid. Requested dimensional and performance data and a factory test report.
Status and next step
A technical comparison enquiry was prepared. The alternative remains subject to documented differences and customer approval.
Technical preparationHigh-pressure package: unit and accessoriesSeparated requirements for the unit, hoses, guns and package documentation.
Task
Steel-structure cleaning required a package with a long hose line and two guns. The requirements concerned the entire system, not the pump alone.
What we prepared
The enquiry separated unit and accessory limits, test documents and protective-equipment scope. Simultaneous station operation and performance at each station were requested separately.
Status and next step
A package enquiry was prepared with a list of technical confirmations. Compatibility and the agreed duty must be established in the manufacturer's offer.
Pumps and relays in these examples were sourced by model, without an established IMPA reference.
An offer with agreed conditions
Materials, design, duty parameters and documents are agreed before ordering. Supplier stock, quantity and lead time are confirmed for the specific offer.
