Liquid Solid Separation Centrifuge
Pusher Centrifuge
B&P Littleford's Liquid Solid Separation Centrifuges are known for relentless productivity in the separation of coarse solids from free-draining crystalline slurries. The products flow in a gentle, single-stage, handling and washing as they are transported through the basket. Our specialists design and construct the Pusher for standard products, but can also customize it in cooperation with customers for special or difficult solid separation applications to optimize efficiency and meet individual requirements.

Liquid Solid Separation Manufacturer
The strengths of the B&P Littleford Pusher Centrifuge are most evident for special separation process requirements:
- Long retention times
- Low solids loss in the filtrate
- Low crystal breakage
- Intensive solids washing
- Drier cake
- Minimum wear
These features make it an outstanding machine for most crystalline products. As a leading liquid solid separation manufacturer, B&P Littleford Pusher centrifuges have amassed an impressive track record for reliability under all kinds of separation service conditions. This dependability is founded in our sound design concepts, precise engineering and top-grade materials.
Some of the notable design features of the B&P Pusher Centrifuge:
- A single-piece reversible wedge-slot screen separates solids and liquids efficiently
- The screen is supported by a centrifugally cast, milled-slot cage basket
- The main hollow shaft, which drives the basket, is carried by widely spaced, heavy-duty bearings
- The hydraulic pump is belt-driven by the main drive motor for energy efficiency, safety and reliability
- The pusher shaft is driven forward and backward by the internal, self-contained hydraulic piston
- This assembly requires no external controls
- The rugged base of the separation pusher houses the hydraulic reservoir and provides rigid support for the entire rotating assembly
- Cooling coils inside the reservoir maintain the hydraulic system temperature to optimum levels

Process Challenges |
Solved by B&P Pusher Centrifuge |
Mean Greater Profits |
|
Cake drying |
Longer retention time on long basket due to slower solids transport speed |
High yield dry cake |
|
Loss of solids to filtrate |
Thicker denser cake acts as an effective intrinsic filtration media and minimizes loss of fines |
Low solids loss to filtrate |
|
Crystal breakage |
No mechanical stress by transporting elements and no tumbling of crystals |
Low crystal breakage and abrasion |
|
Cake purity |
Direct spraying of wash liquid onto cake |
Efficient continuous washing and drying for highest purity and yield |
|
Energy consumption |
Optimized design lowers specific energy consumption (kWh/kg cake) |
Energy-efficient separation, washing and drying |
B&P Pushers are used in a myriad of separation applications such as bulk chemicals, plastics production, mining and minerals, fiber industry, and food processing.
