PV-Belt-Type Side Entry Mixer for large storage tank agitation — prevent sediment, ensure homogeneity, improve heat transfer.
Request a Quote View SpecificationsThe PV-Belt-Type Side Entry Mixer is engineered for reliable agitation of crude oil and various petroleum products in large storage tanks. Installed horizontally on the tank sidewall, it generates controlled flow circulation to maintain product homogeneity, ensure uniform temperature, and prevent sediment — particularly wax and heavy sludge — from settling on the tank floor.
Compared to top-entry mixers, side-entry installation requires no roof penetration, offers lower capital investment, and delivers equivalent or better circulation performance across a wide range of tank sizes. The PV belt drive further ensures smooth power transmission, quiet operation, and minimal maintenance.
Large crude oil storage tanks face a persistent challenge: heavier fractions, waxes, and sediments tend to settle over time, creating stratification that affects product quality, custody transfer accuracy, and tank heating efficiency. A properly sized side entry mixer resolves this by maintaining continuous bulk circulation.
Eliminates dead zones where sludge and wax accumulate on the tank floor.
Consistent density, viscosity, and composition throughout the tank.
Ensures even heating across the tank, reducing energy waste and heating time.
No roof crane access needed; side mounting simplifies installation and maintenance.
Shock-absorbing, low-noise, easy to maintain.
Variable insertion angle covers more tank volume, eliminates dead spots.
Reliable sealing for continuous tank-side operation; no leakage risk.
Side-wall mounting frees up tank roof space for other equipment.
Available for flammable petroleum media in hazardous areas.
Material selection matched to your medium, temperature, and corrosion conditions.
Minimizes static electricity buildup — critical for flammable oil storage.
Drive unit and seal assembly accessible without emptying the tank.
Exact configuration depends on tank geometry, medium properties, and process requirements.

The variable insertion angle (swing angle) feature is specifically designed to combat sediment accumulation across the entire tank floor. By adjusting the mixer's rotation angle, the flow sweep covers a wider area, reaching tank corners and perimeter zones that fixed-angle mixers cannot effectively agitate.
Addresses gradual settlement risk in tanks that hold product for extended periods.
Maintains effective agitation regardless of current tank fill height.
Particularly valuable for waxy, high-asphaltene crude oils prone to solid deposition.
Homogeneous Mixing — Ensure uniform composition throughout the vessel.
Gas Dispersion — Distribute gas evenly within the liquid phase.
Solid Suspension — Keep solid particles (such as catalyst) uniformly suspended.
Liquid-Liquid Dispersion — Suspend or fully emulsify immiscible liquid phases.
Mass Transfer — Improve interphase transfer processes such as absorption.
Heat Transfer — Maintain consistent temperature across the entire tank.
