Azcue SP Series: Includes MO, BO, BR

Self Priming Multistage Side Channel Pump

Flow: <45M³H
Head: 225M
DN: 25-65mm
Temp: < 90°C

The Azcue side channel pumps, ( liquid ring pumps) are able to pump gaseous liquids such as fuel oil, kerosene, diesel and emulsified liquids. Side channel separate air and liquid from the fluid being pumped. This action is achieved by the radial vane impellers and side channels or diffuser holes separating the liquids using centrifugal force.

Azcue self-priming pumps have a high priming capacity, and are able to pump liquids with high air or gas content. As the impeller rotates between the two diffusers, the discharge channel shape and location changes the fluid direction continuously, back and forth from the impeller increasing the fluid pressure, and achieving high discharge pressures in comparison with other pump designs.

The multistage design enables one or several stages assembly. The discharge pressure is directly related to the number of stages. Therefore, the side channel pumps achieve high discharge pressures at low rotating speeds and with much less stages than multistage centrifugal pumps.

Constructive Features:

Maximum Discharge Pressures:

Types MO, BO: 10 bar (1 Mla)
Types BR: 16 bar (1.6 Mla)
The discharge pressure is the suction pressure plus the manometric pressure created by the pump.

Maximum Fluid Temperature:

Standard Version: 90°C
Specially Required: 130°C

Shaft Seal:

Standard Version: Leak-less mechanical seal.
Specially Required: Soft packing.

Rotating Sense View From Motor:

Standard Option: Clockwise.
Specially Required: Anti-Clockwise.

Materials:

The pumps can also be manufactured in different materials as nodular cast iron, stainless and Aluminium Bronze NiALBz

Applications:

The pumped fluid must be clean and without abrasive solid particles.
The side channel self priming pumps SP series have among other, the following features:

*Capacity to pump liquid with air content.
*Excellent self priming capacity.
*Low NPSH required.
*High discharge heads with very few stages. Therefore, these pumps cover a wide range of applications as high temperature fluids, high vapour tension liquids or volatile liquids.

For capacities up to 12 m3l/h and 8 bar pressure, they are many more times economical than centrifugal pumps.

Industries:

• Fuel, petrol, nafta, kerosene, diesel oil.

• Boiler Feed

• Condensed water extraction.

• Chemical products, emulsified fluids etc.

In general, all kinds of clean liquids with difficult suction conditions.

Marine:

• Fresh water and sea water sanitary services.

• Sanitary hot water circulation.

• Condensed water extraction on fresh water generators.
