05PUMPS & PRESSURE SYSTEMS

We don’t look at a pump on its own, but as part of the system it serves.

01Which problems do we solve?

  • Is the pump not running?
  • Is it not building pressure?
  • Is it running continuously?
  • Is it cycling on and off too often?
  • Is it noisy?
  • Is it leaking or tripping the fuse?

Starting from the symptom, we check the suction line, pump, check valve, expansion tank, pressure switch and power supply in turn to find the root cause.

02Scope of service

Pumps & pressure systems

Selection, installation, maintenance, fault finding and testing of hydrophore, transfer and sea water pumps.

  • Hydrophore systems
  • Fresh water pressure pumps
  • Transfer pumps
  • Sea water pumps
  • A/C sea water circulation pumps
  • Bilge pumps
  • Grey / black water transfer pumps
  • Fuel transfer pumps
  • 12 V / 24 V DC pumps
  • 220 V / 230 V AC pumps
  • Pump replacement and new installation
  • Basic mechanical and electrical fault finding
  • Pressure switch check and setting
  • Expansion tank / accumulator check
  • Check valve, valve and connection checks
  • Suction and discharge line checks
  • Leak checks
  • Flow and pressure checks
  • Commissioning and function testing

Pump types

  • Centrifugal
  • Jet
  • Diaphragm
  • Vacuum
  • Gear
  • Screw
  • High pressure
  • Submersible

Hydrophore systems

  • Pump replacement
  • Expansion tank pre-charge
  • Pressure switch cut-in / cut-out setting
  • Check valve tightness
  • Pump control systems

Hydrophores, pressure problems, expansion tanks and pump controls are among the most frequent service calls on boats.

03How does the system work?

A pump is part of a system.

  5. 05Check valve
  6. 06Pressure system
  7. 07Point of use

  3. 03Expansion tank
  4. 04Pressure switch
  5. 05Distribution line

Choosing the right pump is not about flow rate alone: voltage, pressure demand, flow, head, suction conditions, pipe diameter, line losses and purpose are assessed together.

04Our service approach

“Choosing the right pump is not about flow rate alone.”

We assess voltage, pressure demand, flow, head, suction conditions, pipe diameter, line losses and purpose together with the existing system. Our aim is not to sell a product, but to have the pump work efficiently, in harmony with the system and in a serviceable way.

05Service process

From survey
to service report.

Our goal is not just to get a system running again, but to hand it over correct and serviceable.

  1. 01

    Symptom & system check

    Pump, lines, tank and control elements are inspected under operating conditions.

  2. 02

    Fault diagnosis

    Basic mechanical and electrical checks identify the source of the problem.

  3. 03

    Selection & plan

    Repair, adjustment or replacement — with a pump selected to suit the system where needed.

  4. 04

    Installation / replacement

    Pump, check valve, expansion tank and connections are installed.

  5. 05

    Pressure, flow & function test

    Pressure, flow, cut-in/cut-out and leaks are checked and the system is commissioned.

06Systems / brand examples

We work on 12/24 V DC and 220/230 V AC pumps from different manufacturers, following manufacturer data for selection and installation.

07Real applications

All projects
  • Extensive field work on hydrophores, transfer and bilge pumps, pressure systems and auxiliary pumps
  • Pump replacement, expansion tank and pressure problem service calls
  • Pump system installation on new-build and refit projects

08Frequently asked questions

Good
questions.

Can’t find your answer? Just tell us the system and the marina.

Ask a question
Why does a hydrophore keep cycling?

Most often: low expansion tank pre-charge or a failed membrane, a leaking check valve, a small leak in the line or an incorrect pressure switch setting.

What matters when choosing a pump?

Voltage, pressure demand, flow, head, suction conditions, pipe diameter, line losses and purpose — assessed together.

Can a different brand replace my existing pump?

Yes, if connection sizes, voltage, flow/pressure values and installation conditions match. We make the selection together with the system.

Next step

Let’s solve your pump together with its system.

Tell us the pump type, voltage and symptom; a photo of the label speeds up the diagnosis.
