Liverani GR ADPE Explosion Proof Side Channel Pump

The Liverani GR ADPE Series are long coupled, Explosion Proof (II 2G IIC c T4 X / II 2G IIB c T4 X) side channel pump. These liquid ring pumps are frequently used in many industries for the transfer and offloading of clean, low viscosity and flammable fluids such as light hydrocarbons including Aviation Fuel / Kerosene, Petrol & Diesel as well as alcohols, acids, solvents & edible fluids.

The GR ADPE side channel pumps are an incredibly robust and versatile pump, offering a varied flow and head range as well as motor voltage options and control options. They are supplied either on a baseplate or trolley for portable applications.

Features of the GR ADPE Series Liquid Ring Pump:

• Explosion proof, long coupled liquid ring pump
• Self priming up to 6m without the need of a non return valve
• Reversible operation
• Low risk of cavitation due to low NPSHr
• Short period of dry running
• Hygienic construction
• Transfer of fluids with gases and vapour in suspension without a pulsing effect
• Single bearing and sealing construction up to MASTER 2”, NAUTIC 70 & 80 units fitted with double bearing and sealing construction - reducing shaft deflection and wear & increased leakage protection
• Supplied with BSP M Fittings as standard. Can be supplied with a variety of food grade connections and also custom welded flange configurations. See case study here.
• Operating Speeds up to 2800 rpm
• Trolleys fitted with Anti-Static Wheels
• Stainless Steel Impellers available for Stainless Pump Heads. Fitted with Bronze as standard (except NAUTIC 80 in SS)
• Single Phase motors available for up to MASTER 2” / SPECIAL 50

Thanks to the following features the Liverani GR APDE side channel pump is an option that can be applied to many application requirements.

• ATEX approved - Explosion proof motor for the safe handling of flammable liquids and hydrocarbons
• Hygienic construction - The Stainless Steel model is food grade making it safe for use with products for human consumption. Tri-clamp coupling available.
• High entrained gas capabilities - Liquids with up to 50% gas content can be handled without any dry run damage e.g condensate
• Low NPSH required - Can pump liquids close to boiling point without risk of cavitation such as LPG 
• High temperature handling - Liquids can be transferred at temperatures up to 165°C which is where other pumping technologies fail
• Reversible operation – Allows cleaning solution to be ran through after use for hygienic pump applications, and tank to tank transfer applications.
• Self-priming up to 6m – Enables the emptying of tanks and drums without a non-return valve or regular manual priming being required.
• Various accessories available - Trolley for portability, bypass valve for nozzle dispensing, control panel, variable speed drive, level sensors and dry run protection

Like centrifugal pumps, side channel pumps have narrow tolerances that make them suited to only clean, low viscosity fluid free from solids. However, their uses do vary. Firstly, side channel pumps can handle high temperature fluids that are pumped close to boiling point and also can pump fluids that contain up to 50% gas content with little interruption to fluid flow. Their hygienic design and their reversible operation means that the Liverani GR APDE liquid ring pump is ideal for the below applications:
