From light fuels and solvents to heavy oils, resins, and polymers, they deliver consistent, accurate flow even in the most challenging applications. Need precise dosing, reversible flow, or a pump that can be jacketed to maintain temperature integrity? Round Arc Internal Gear Pumps provide the versatility, ruggedness, and efficiency that ensure your operation runs without interruption.

SPEW SRA Series: Backed by proven engineering and dependable performance, these pumps are the trusted choice for industries that demand safety, precision, and peace-of-mind fluid handling.

Features

“FLOTAN” SRA Series Internal Gear Rotor Pumps offer several key advantages, making them highly suitable for industrial fluid handling. They provide smooth, low-pulsation flow at high viscosities, ensuring gentle handling of sensitive liquids. FLOTAN SRA self-priming capability and ability to operate in both directions make them versatile for a wide range of applications. With high volumetric efficiency, they can deliver accurate, consistent flow rates across varying pressures. These pumps are also known for their compact design, quiet operation, and long service life, thanks to fewer moving parts and robust construction, making them reliable and cost-effective solutions for transferring fuels, oils, chemicals, and other viscous fluids.

Advantages

  • Steady delivery without pulsation, little vibration & noise and outstanding self-priming ability.
  • The pump can deliver the varied corrosive medium fluids if suitable material of constructions are selected. In addition, the working temperature can bear up to 200℃ easily.
  • The same rotary direction of internal rotor and outside rotor results in little wear and long operational life.
  • The pump’s flow capacity can be changed through adjusting the speed.
  • It’s suited to deliver high viscous medium.

Structures

  • The pumps are mainly composed of internal rotor, outside rotor, shaft, pump casing, front cover, seal, bearing etc.
  • The pump seal adopts packing seal or mechanical seal. When the delivered medium is high temperature, high viscous or strong corrosion, packing seal should be adopted.
  • When the delivered medium is ease crystalline, we can design the heat preservation jacket in the pump casing and front cover in order to melt the medium with steam when working. The pump can be also fitted with the safety valve.
  • The pump set is composed of the pump, motor and baseplate. the direction way is belt wheel driving or coupling driving.
  • The direction of rotation is clockwise viewed from coupling end.
