The Azcue CA ATEX Close Coupled Centrifugal Self Priming Pump is a competitively priced, compact single stage centrifugal pump with good flow and pressure capabilities. As its inlet is towards the top of the casing, the CA is able to run dry for 30 minutes as they can hold a significant amount of liquid in the casing once initially primed. This makes the CA self priming pump is ideal for the transfer of clean fluids such as water and light fuels over long suction distances, where the tank is situated below the pump and for giving some leeway before the pump needs to be turned off .

With the option of a semi-open impeller, the Azcue CA horizontal centrifugal pump is able to handle up to 10mm of soft solids, making it compatible with water with some degree of contaminants. This series of centrifugal water pump benefit from a back pull out design, meaning that the motor can be removed without disconnecting the pump from the pipework, which is time saving and less complex when maintenance is required.

Whilst being closed coupled, the CA self priming centrifugal pump has a lantern bracket, which means that whilst being space saving in design, there is still some separation the pump and motor so should the seal fail fluid will not enter the motor. It can also be supplied as a bare shaft pump head for fitting to a motor and making it long coupled. This version has additional bearings in the pump head to share the strain of operation, therefore enhancing the robustness of the pump for continuous use.

These Azcue pumps have a separate shaft in the pump head and motor meaning that if one shaft goes, there is no need to replace it all; a benefit over other pumps on the market that have one continuous shaft from head to motor. This model has wear rings, which means there is small clearance between the impeller and pump casing preventing wear to these parts. Wearing rings are designed to be replaced periodically which stops the more costly replacement of the impeller or casing.

Sea Water Injection - Long Coupled Self Priming Centrifugal Pumps

Sea Water Injection - Long Coupled Self Priming Centrifugal Pumps

Castle Pumps are able to supply pumps for both marine and industrial applications, and pride themselves on supplying pumps that best match the customers requirements. This enquiry was for self priming sea water injection pumps but the customer requested that the material be stainless steel 316, rather than the recommended material of bronze. We were able to provide a suitable pump that matched the customers requirements and which came in the requested material of stainless steel.

Seawater Containing Sand for Marine Dredging - Self Priming Centrifugal Pumps

Castle Pumps understand that for some companies the lead time on wearing parts is one of the most important factors, and therefore ensuring access to local stock is vital. In this example, we were able to improve on the previous supplier's lead time on spare parts by three weeks. As pump downtime for a dredging company is very costly, the customer was hugely impressed with our service.

The CA Close Coupled Centrifugal Pump is manufactured by Azcue Pumps. As the official UK Agent of Azcue Pumps, Castle Pumps are a leading Bombas Azcue supplier in the UK with unrivalled technical knowledge. Azcue Pumps are a European manufacturer with over 100 years’ experience in type approved pumps for marine and offshore applications. Today their pumps are installed in more than 10,000 vessel builds. Whilst originally developed for the marine market, Azcue Pumps’ reliability in applications that depend upon the safety and operation of a ship saw them become a desirable product in industrial applications involving water, fuels and lubricants.

One of the key benefits of the CA single stage centrifugal pump like the other models in the Azcue range, is that is benefits from interchangeable parts for reduced on board stockholding. We guarantee supply of spares for 15 years from model discontinuation for long term pump servicing., saving the user from having to prematurely replace a pump that just needs maintenance.

Azcue CA self priming centrifugal pump are cast, machined and assembled at their foundry in Spain. Each pump is manufactured to order and designed to fit your process, resulting in greater efficiency and lower overall lifetime cost in terms of wear and energy consumption. Before leaving the factory, pumps are individually tested to confirm performance meets the requirements set out in your enquiry.

Centrifugal pumps are the most common pump type for the transfer of low viscosity fluids in high flow rate and relatively low-pressure installations. The centrifugal pump design is often associated with the transfer of water, but is also a popular solution for handling thin fuels and chemicals. This combined with its self priming ability makes the Azcue CA close coupled centrifugal pump suited to applications including:

Marine Applications:Industrial Applications:
  • Sea water cooling pump
  • General sea water service
  • Grey water pump
  • Aquaculture circulation systems
  • Ballast water pumping
