The Rotoliptic Design
The core innovation behind Rotoliptic pumps is an elliptical rotor and continuous rotary mechanism in a positive displacement assembly. Critically, a Rotoliptic pump is simply two moving parts.
The Rotoliptic Pump
Rotoliptic is a patented positive displacement pump design capable of handling fluids with high viscosity and solids content, such as fluids with sands and fines. Our design maintains efficiency over a broader range of viscosities and can pump high gas fractions. The result is a robust, economical, drop-in replacement pump, which is easily scalable in stages.
Rotoliptic is currently applicable to 15% of the $65B global pump market. Pronounced interest from the electronic submersible pump (ESP) industry has fueled initial product focus on oil and gas, specifically artificial lift. With reduced drive strain, Rotoliptic will promise longer life, less maintenance and downtime, and substantial savings on total cost of ownership.
Existing centrifugal pump designs struggle to maintain efficiency; specifically, they fail to maintain best efficiency point (BEP) throughout their lifespan. Pump efficiency is vulnerable to pressure, flow rate, and viscosity fluctuations, and currently, the incumbent’s performance plunges with high viscosity. Notably, Rotoliptic pump efficiency is remarkably more immune to both varying viscosity and flow rate.
