The Azcue LD ATEX is a split casing pump, which is essentially a single stage centrifugal pump with a double suction impeller supported between bearings, splitting the pump case into two separate chambers. This double suction centrifugal design means that the LD is capable of much higher flow rates at lower pressures than alternative vertical centrifugal pumps, making them suitable for high volume transfer of thin, clean fluids like water.

The LD vertical split case centrifugal pump is a long coupled pump, making it easier to maintain as you can get to the pump head without removing the motor first, and more durable for continuous use as it has additional bearings in the pump head to share the strain of operation. A further benefit of this centrifugal water pump are the separate shafts in the pump head and motor, meaning that if there is a problem with one, the whole thing doesn’t need to be replaced. Thanks to its wear rings, there is small clearance between the impeller and pump casing preventing wear to these parts. Wearing rings are designed to be changed periodically, preventing the more expensive replacement of the impeller or casing.

These Azcue split case centrifugal pumps are available to be supplied with an external priming pump either VP (vacuum priming pump) or EP (electric priming pump). With a vacuum priming pump it can dry run for a short period of time, making this a better option than an electric priming pump for longer suction distances.

Features of the LD Vertical Inline Pump:

  • Long coupled, vertical double suction centrifugal pump
  • ATEX approved
  • Pump manufactured in Spain
  • Marine type approved by all classification societies
  • Flexible rather than rigid coupling to help absorb vibrations
  • Compact vertical design ideal for space saving installations
  • Available in cast iron, 316 stainless steel and bronze for seawater
  • Additional bearing between pump and motor to share strain
  • Back pull out design for simple maintenance
  • Separate shafts in the pump and motor
  • Low NPSH
  • Casing wear rings to prolong casing and impeller life
  • 230v, three phase 50Hz/60Hz motors available. IP55 as standard.
  • Available with a vacuum or electric priming pump on request
  • Supplied flanged as standard

The Azcue LD vertical double suction centriifugal pump is available with the following material options:

G-Cusn5ZnPb (Rg5)
G-CuSN10Zn (Rg10)
X5CrNiMO 18 10

The LD Split Case 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 LD double suction 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 LD split casing pumps 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.

Single stage 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. Their ultra high flow capabilities combined with its motor being located above the pump head, makes the Azcue LD double suction centrifugal pump suited to large volume applications where installation space may be limited including:

Marine Applications:Industrial Applications:
  • Sea water cooling pump for large equipment and vessels
  • General sea water service
  • Grey water with low solid content
  • Aquaculture recirculation systems
  • Large scale marine ballast water pumping
  • Low viscosity fuel and lubrication transfer
  • Boiler feed pump
  • Closed loop HVAC circulating and cooling tower pumps
  • High volume general water transfer, supply and service
  • Waste water with low solid content
  • Water pressure booster pump
  • Swimming pool recirculation systems
  • Low viscosity fuel and lubrication transfer
  • Boiler feed pump
