Pumps & Fluid Handling Solutions
Reliable marine and industrial pumps from Mari Zul
Mari Zul supplies dependable pumps, pump spares and fluid-handling components for marine, offshore, commercial and industrial applications. From routine maintenance to urgent replacement requirements, we help customers source practical equipment solutions for moving water, fuel, chemicals, sewage, sludge and other process fluids safely and efficiently.
Our range supports essential duties across vessels, ports, shipyards, offshore operations, fishing fleets and industrial facilities throughout South Africa and beyond. Whether the requirement is for bilge and ballast management, fire protection, fuel transfer, cooling-water circulation, freshwater supply, hydraulic systems or wastewater handling, we can assist with pumps and compatible supporting components.
We supply a broad selection of pump types, including centrifugal, positive displacement, vacuum, chemical, sewage, sludge and transfer pumps. To help keep systems operating reliably, Mari Zul also sources pump spares and maintenance components such as mechanical seals, bearings, impellers, gaskets, O-rings, hoses, fittings, couplings, valves, strainers and filters.
Every application has different operating demands. Fluid type, flow rate, pressure, temperature, viscosity, solids content, power supply and the installation environment all influence the correct pump selection. Our team works with customers to understand these requirements and source suitable equipment for both new installations and replacement needs.
From a single critical spare to a wider pump and fluid-handling procurement requirement, Mari Zul is committed to responsive service, dependable quality and practical support. Share your specifications, existing pump details or application requirements with our team, and we will help identify a solution that supports safe, efficient and reliable operation.

Pump maintenance tips
Check for leaks early
Inspect seals, connections and housings regularly. Small leaks can indicate worn seals or failing components before they become a major breakdown.
Keep strainers and filters clean
Blocked strainers restrict flow and place unnecessary load on the pump. Clean them as part of planned maintenance.
Monitor unusual vibration or noise
Excessive vibration, noise or heat may indicate bearing wear, misalignment, cavitation or an obstruction in the system.
Use the correct pump materials
For seawater, chemicals and abrasive fluids, ensure wetted components and seals are compatible with the fluid to prevent corrosion and premature failure.
Keep critical spares available
Mechanical seals, bearings, impellers, gaskets and couplings are worthwhile stock items for essential pumps and high-demand systems.
Frequently asked questions
What type of pump do I need for bilge water?
Bilge-pump selection depends on the vessel size, required flow rate, power source, debris risk and operating conditions. Strainers and corrosion-resistant materials are important considerations.
Can Mari Zul supply pump spares?
Yes. We supply pump spares including mechanical seals, bearings, impellers, gaskets, O-rings and related fluid-handling components.
What is the difference between centrifugal and positive displacement pumps?
Centrifugal pumps are commonly used for lower-viscosity fluids and continuous flow applications. Positive displacement pumps are better suited to thicker fluids, controlled flow and higher-pressure duties.
Can you assist with chemical pump selection?
Yes. Share the chemical type, concentration, temperature, flow and pressure requirements so that a compatible pump material and seal arrangement can be sourced.
What details should I provide for a pump quote?
Include the pump type or existing model, fluid being transferred, flow rate, pressure, power supply, inlet and outlet size, operating temperature and delivery location.
