The Azcue VM & VR VP/EP Self Priming Vertical Inline Pumps are an ATEX rated version of the VM & VR close coupled vertical centrifugal pumps. They come complete with a vacuum or electric priming pump and are suitable for applications difficult suction conditions. For longer distances, a vacuum priming pump is recommended due to its ability to dry run for short periods of time.

The VM & VR vertical inline centrifugal pumps are an alternative to the LN, but are more heavy duty and bigger, with higher flow and pressure capabilities. Most suited to applications involving relatively clean liquids such as water and thin fuels, they are also ideal for installations where space saving is important. Unlike the VM, the VR single stage centrifugal pump has an extra ball bearing between the pump and motor which helps share the strain of operation, resulting in it being a more robust option than the other within critical applications.

The Azcue VM/VR vertical self priming centrifugal pumps benefits from a back pull out design whereby the motor is able to be removed from the pump, without having to completely disconnect it from its installation – a time saving advantage during maintenance. Strictly speaking this pump is close coupled, but these centrifugal water pumps have a lantern bracket which creates space between the pump and motor, whilst still being compact. So if the seal ever wears, fluid won’t fall into the motor.

These Azcue ATEX vertical inline pumps have one shaft in the pump head and another in the motor, so that if an issue was to ever occur in one shaft, there is no need to replace it all – a benefit which alternative pumps on the market don’t possess, as they have a continuous shaft from head to motor. Also included are wear rings, generating a small clearance between the impeller and pump casing, resulting in less wear to parts. Wearing rings only need to be replaced periodically, stopping the more costly replacement of the impeller or casing.

• Close coupled, single stage vertical centrifugal pump
• ATEX rated to zone 1
• Comes with either vacuum or electric self priming pump
• VR version has additional bearing between pump and motor to share strain
• Pump manufactured in Spain

Castle Pumps have built solid relationships with many industrial pump manufacturers, which gives us confidence in our ability to meet tight project time scales. This case study illustrates this, where we were able to get two ballast pumps manufactured and marine certified in three weeks less than the industry standard lead time.

The Azcue CM ATEX Vertical Inline Pumps are larger and tougher vertical centrifugal pumps than the LN range, have higher flow and pressure abilities and come with an ATEX rating. These pumps are ideal for space saving and are suitable for applications involving relatively clean liquids such as water and thin fuels. Similar in design to the VR single stage centrifugal pump, the CM has an extra ball bearing between the pump and motor to share the strain of operation and has the addition of a spacer coupling so that maintenance can be undertaken without having to remove the motor.

The Azcue CM vertical inline centrifugal pump is a back pull out pump which means the motor can be removed without the need to completely disconnect the pump from the installation, which saves time during maintenance. Strictly speaking the CM is a close coupled pump, and whilst they are compact, these centrifugal water pumps have a lantern bracket which offers space between the pump and motor – meaning if the seal fails, no fluid will fall into the motor.

These ATEX vertical inline pumps from Azcue have one shaft in the pump head and another in the motor; so if there’s ever an issue with one, there’s no requirement to replace it all – a benefit which other alternative pumps don’t have, as they usually have one continuous shaft from head to motor. This model has wear rings so there is small clearance between the impeller and pump casing preventing wear to these parts. Wearing rings are designed to be changed intermittently, avoiding the costly replacement of the impeller or casing.

Versions with an external vacuum or electric priming pump are available for this CM spacer coupled centrifugal pump, or when suction conditions are difficult, a vacuum priming pump should be chosen because of its ability to dry run for short periods of time.

Subsea Oil/Gas Company

This existing customer needed to upgrade their fire pump system on board their vessel and decided to contact us due to our reliability with past projects we have done for them. Due to the extensive knowledge and experience we have on the marine sector, Castle Pumps were able to meet the customers specific requirements and provide them with an ideal pump which was manufactured and marine certified in fewer than 8 working weeks.

The Azcue KB Progressive Cavity Pump is a quality and robustly constructed solution designed the transferring of difficult fluids even over long distances thanks to the high pressures they can achieve. Thanks to its low internal velocity of helical rotor pumps, the KB can transfer viscous liquids containing particles and contaminants efficiently such as sewage and slurries, as well as shear sensitive mediums that have a structure can be impacted when high shear is applied.

The KB is a more compact and cost effective progressive cavity pump compared to the KL model, as rather than having a bearing bracket, the motor is close coupled directly to the pump housing. Available in smaller sizes and at lower flows than the KL, it is ideal for less abrasive conditions and smaller volumes of liquid being transferred, whilst still being able to handle solids up to 95m.

In order to ensure reliable operation and a long service life, the KB eccentric screw pump has a fully encapsulated cardan shaft and joint with lifetime lubricated needle roller bearings that prevent wear and mean they don’t need to be regularly maintained. It also benefits from joint connections that have continuous diameters, ensuring there is a constant flow within the suction housing and blockages do not occur.

For more information on how progressing cavity pumps operate and the applications for which they are most suited, read our guide.

• High pressure progressing cavity pump
• Self priming to handle difficult suction conditions
• Enables the free passage of solids up to 95mm
• Max viscosity of 200,000 mPas

Material options for the KB eccentric screw pump:

The Azcue KL Progressive Cavity Pump is a large, robustly constructed solution designed for harsh pumping conditions thanks to their ability to handle difficult fluids even over long distances thanks to the high pressures they can achieve. The low internal velocity design of the eccentric screw pump means that the KL can transfer extremely viscous fluids containing solids effectively such as sewage and slurries, as well as shear sensitive fluids than need to maintain their structure during the pumping process.

With higher flow and higher solids handling capabilities (up to 150mm) than the KB, the KL progressing cavity pump is the ideal option for more heavy duty applications where larger volumes of fluid need to be transferred or the media has particularly large and abrasive contaminants.

Whilst being closed coupled, the Azcue KL helical rotor pump has a bearing bracket which is coupled to the motor via a plug connection which is easy to service and relieves the strain on the shaft and gears, making them suitable for continuous application. This bracket also means that there is still space between the pump and motor so in the case of seals wearing out, water leaked from the pump head would not enter the motor.

Other design benefits of the KL Azcue pump is its fully encapsulated cardan shaft and joint as standard with lifetime lubricated needle roller bearings that are wear and maintenance free. Its joint connections, which have equivalent diameters, ensure a constant flow within the suction housing to prevent blockages in the pump.
