Why Fluidite
Key Features
Precise & Gentle
Gentle handling for shear-sensitive products. Low rotational speeds and large fluid pockets protect fragile emulsions, live cultures, and fruit pieces.
Reliable Performance
Built for continuous and long-lasting operation. External timing gears ensure lobes never contact each other or the casing.
Self-Priming Capability
Can self-prime up to 6 metres. Ideal for completely emptying tanks and hoppers without a foot valve or flooded suction.
Precise Metering
Flow rate is directly proportional to pump speed. Adding a VFD provides precise, repeatable metering control — ideal for dosing and filling lines.
How It Works
Working Principle
1
Fluid Entry
Fluid enters the pump as the lobes create a vacuum.
2
Fluid Trapped
Fluid is gently trapped between the lobes and the casing.
3
Lobe Rotation
Lobes rotate, carrying the fluid towards the outlet.
4
Smooth Discharge
Fluid is discharged smoothly with minimal shear.
Engineering
The Lobe Pump Mechanism
Four principles behind every Fluidite lobe pump.
01
Synchronized Lobe Rotation
External timing gears in the sealed gearbox keep both lobes perfectly synchronized. The lobes never contact each other or the casing, eliminating mechanical wear on the product stream and providing long, maintenance-free service life.
Reliable Performance02
Gentle, Low-Shear Transfer
Low rotational speeds and large fluid pockets mean the product is displaced gently. Fragile emulsions, live cultures, fruit pieces, and shear-sensitive bioproducts are transferred without damage or loss of product integrity.
Gentle on Products03
Flow Proportional to Speed
Because every revolution displaces a fixed volume, flow rate is directly proportional to pump speed. Fitting a variable-frequency drive (VFD) provides precise, repeatable metering control — ideal for dosing and filling lines.
Precise Metering04
Self-Priming Capability
The expanding cavity at the inlet creates a vacuum that draws product in without a foot valve or flooded suction. Fluidite pumps can self-prime up to 6 metres, ideal for emptying tanks and hoppers completely.

Product Range
Fluidite Lobe Pump Series
Four series engineered for different process demands.
High-Viscosity Pump
Jacketed Series
Jacketed type lobe pumps are specially designed for handling temperature-sensitive and high-viscosity products that require heating or cooling during transfer. The pump casing is provided with an external jacket (chamber) through which steam, hot water, or thermal oil circulates to maintain the desired product temperature. This prevents solidification, crystallization, or viscosity increase, ensuring smooth and continuous pumping.
Highlights
- Temperature-sensitive products
- High-viscosity fluids
- Prevents solidification & crystallization
- Steam / hot water / thermal oil jacketing
Compact Inline Pump
Standard Series
Low-profile inline configuration for space-constrained installations. Extended shaft option for direct-drive or belt-drive coupling. Stainless pump head with threaded outlet connections. Heavy-duty lobe pump with tri-clamp inlet/outlet connections. Designed for cream, butter, pastes, and thick sauces. Blue-coated gearbox with polished SS 316L pump head. Ideal for products up to 1,000,000 cP.
Highlights
- Space-constrained installations
- Direct-drive or belt-drive coupling
- Tri-clamp inlet/outlet connections
- Up to 1,000,000 cP viscosity
Heavy Duty Pump
Special Purpose Series
This specific configuration is designed to handle highly viscous, semi-solid, sticky, or chunky products that cannot easily flow through standard circular pipes or tend to bridge and block a conventional inlet.
Highlights
- Highly viscous & semi-solid products
- Sticky or chunky materials
- Non-standard inlet configurations
- Heavy duty construction
Complete Motor-Mounted Set
Trolley Mounted / Customized Series
Trolley-mounted (or mobile) rotary lobe pumps are used wherever process fluids need to be transferred across multiple locations within a facility, or when a temporary, flexible pumping solution is required. Instead of being bolted down in a fixed pipework system, the pump, motor, and gearbox drive are integrated into a compact, wheeled stainless steel or heavy-duty steel cart (trolley).
Highlights
- Mobile across multiple locations
- Pump + motor + gearbox integrated
- Wheeled stainless steel cart
- Flexible temporary solution
Applications
Products We Handle
Viscous & hygienic fluids across food, dairy, and pharmaceutical industries.
Fresh & Processed Cream
Gentle handling preserves the emulsion structure essential to whipping performance.
- Suitable for single cream, whipping cream, coffee cream, and clotted cream transfer
- Ideal for bulk tanks to filling lines
- Low shear at slow lobe speed prevents fat globule rupture, maintaining texture and yield
Tomato Ketchup & Purees
High-viscosity tomato products with fruit and seed particulates are conveyed smoothly without separating solids from the liquid base.
- Large lobe cavities handle pulp concentrates up to 36° Brix without blocking or pulsation
- Suitable for hot fill at up to 95°C
- Ensures consistent flow and product quality with minimal product degradation
Aloe Vera Pulp & Gel
Fragile aloe gel matrix is transferred completely intact — no degradation of active polysaccharides or aloin constituents — for cosmetic, personal care, and nutraceutical applications.
- Short path length and CIP-clean wetted parts ensure zero contamination
- Suitable for cosmetic, personal care, and nutraceutical applications
- Product purity maintained throughout transfer
Butter & Ghee
Semi-solid fats at temperatures between 40°C and 80°C are pumped without smearing, churning, or heat build-up.
- Jacketed pump head option maintains butter at precise temperature
- During transfer to moulding or packaging lines
- No smearing or churning of product
Curd / Set Yoghurt
Delicate curd structure is maintained through slow lobe speed and gentle displacement.
- Ideal for set curd, Greek-style yoghurt, flavoured yoghurts, and live-culture dairy products
- Shear would damage the protein matrix and affect mouthfeel — lobe pump prevents this
- Slow lobe speed preserves delicate curd structure
Groundnut / Nut Paste
Dense, high-fat pastes with abrasive solid particles demand special attention.
