Side Entry Mixing System

Our BSER side entry mixer drive combines with our Forward Rake Advanced Pitch Propeller that creates a collimated flow for optimal BS&W (bottom, sediment and water) control, faster blending and energy efficiency.

Description

Applications
Petroleum storage tanks for refining, pipelines and storage

Rugged transmission
High-torque toothed belt drives provide long and trouble-free mixer operation

Durable motor mount
Rigid motor mounting provide better reliability and extended drive belt life

Cartridge seal
For ease of field replacement

Unique shut-off device
Positive locking, corrosion resistant, stainless steel metal-to-metal tapered seat faces ensures zero leakage. Environmental spill risk and provides a safer work area for staff. No need to empty tank for routine maintenance. Our shutoff is rated for extended periods of time – only one shutoff method is ever required.

Swivel angle option
60° rotation of mixer ensures the tank floor is scoured to effectively prevent bs&w build-ups. The
Swivel ball is sealed with a hydraulic ball seal for zero leakage.

Stainless steel shaft
This one piece design eliminates corrosion and maintains the integrity of the tank shutoff device.

Superior propeller design
The forward rake propeller utilizes the latest technology in propeller design. The patented geometry creates a stronger collimated flow across the tank to produce up to a 40% improvement in efficiency.

Motor options
IEC/NEMA Frames, Arctic Duty, Explosion Proof, Chemical Duty, Tropical Duty, UL, CUL or CSA Motors, IEEE 841, ATEX.

Rapid and economical maintenance
Deep groove ball bearings mounted on sleeves protect the shaft from damage during operation and maintenance. These bearings have a minimum L-10 bearing life of 60,000 hours.

Fixed angle design
The BSER is also available in fixed angle configurations for blending applications.

Automatic swivel option
Allows the mixer to be automatically adjusted to desired angles without manual adjustment.

Impellers
Advanced Pitch Propeller

Capabilities

Side-entering mixers installed in oil storage tanks are required to perform two main tasks.

These are:

  • Mobilization of sludge that settles on the base of the tank. If sludge is allowed to accumulate it can cause corrosion problems, since it contains some water, and reduce the available operating volume of the tank.  If the agitator cannot achieve this level of mixing the tank must be taken out of service on a regular basis for cleaning at a cost of several hundreds of thousands of dollars.
  • Blending of the contents to ensure that the product leaving the tank has uniform gravity, viscosity and temperature. This is crucial for ensuring that accurate sampling can be achieved.  Also, the time taken to achieve homogeneity determines the productivity of the plant since the tank cannot be emptied until an accurate sample has been obtained.

The patented Lancer Advance Pitch Propeller has been developed to address both these mixing tasks.  It generates a collimated flow to maximize the velocity across the floor of the vessel which mobilizes the sludge and it maximizes the velocity of the vertical flow up the opposite wall of the tank and impinging on the interface between the oil’s heavy and light components.  This ensures that the light component is disturbed and drawn down into the heavy component and blended.

The increased efficiency of the Lancer Advanced Pitch Propeller allows sludge mobilization and blending to be achieved with lower power requirements than agitators fitted with traditional style propellers.

The BSER Mixing System has been developed using feedback from customers to make it easy to maintain by, for example, making openings in the housing larger to allow easier access to bearings and the seal.
