Plenty Mixers -

The Standard for Oil Storage


Plenty Side Entry Mixers have helped to set the industry international

standard. They can outperform other mixers on the market simply by virtue of their technically advanced design, which includes a simple and easily maintainable design, as well as a high efficiency, true helical pitch one piece ‘cast’ impeller incorporating high blade area and forward rake which was developed by Plenty.


Backed by over 60 years operating experience Plenty Mixers, an SPX Brand, has a reference list of successful site installations that is second

to none. Plenty Mixers are acknowledged to be the market leader in the field of side entry mixing technology for the oil and petrochemical

industries, having supplied literally thousands of units worldwide to numerous major oil companies in over 60 countries around the globe.



Unique Tank Shut-Off Device


All units incorporate a tank shut-off device to allow the shaft seal and bearings to be changed under full tank conditions. The tank shut-off mechanism incorporates tapered metal to metal faces, positively clamped by a bolted flange which both seals products in the tank and securely supports the shaft during bearing and/or shaft seal changes.



All tapered faces are wear and corrosion resistant. The most important aspect of the Plenty Shut-off and mechanical seal assembly is that it incorporates a safety check valve for ensuring that the shut-off is 100% effective before removal of any bearings or the mechanical seal. The Plenty shut-off mechanism offers complete safety and security as it does not incorporate any flexible ‘O’ rings or gaskets which may deform, wear, or perish.



Maintaining Homogeneity

To maintain homogeneity of refinery finished or intermediate products or chemical plant feed stocks to ensure uniform specification. This demands complete movement throughout the tank with top to bottom “turnover” as well as circulation round the tank, to ensure that the product at the top, middle and bottom remains uniform to specification.



To mix two or more different components to obtain a homogeneous blend in a specified time to specific requirements again demands complete top to bottom “turnover”.


Temperature Uniformity

To aid heat transfer while heating or cooling or to maintain temperature uniformity - again complete fluid motion, top to bottom “turnover” would normally be required. Location of mixers relative to the heating element is also important to the success of the operation.


Combined Duties

It is possible that one or more of the duties may apply to a particular application and the most critical duty must determine the selection of mixer.



Generally the most power demanding duty is blending.
