SCROLL PUMP
Oil free pumping for Genevac Centrifugal Evaporators
Developed by BOC Edwards, with assistance from Genevac, and based on the "scroll" principle. The scroll pump takes it’s name from the design of
the pump head, where a series of crescent shaped scrolls cut into an oscillating rotor are used to repeatedly compress and decompress the gas or vapour to be pumped.
The main advantage to the scroll pump is that it is "dry" and therefore does not require any pumping fluid or lubricant in order to operate. This in turn makes them ideal for use in harsh chemistry environments such as high throughput chemistry and drug discovery, where corrosive or volatile solvents are frequently used. Ordinary pump designs are totally unsuitable in these labs and so Genevac designed their unique Cole principle vacuum pump for just this type of work. Whilst the Cole principle pumps have been a great success, with over 1000 in use worldwide, they do require occasional topping up of the inert fluid in the pumping chamber, something no longer required with the scroll pump design.
Scroll technology is not new; it has been in use in the microprocessor industry for several years, but this is the first time it has been successfully applied to a wider range of solvents in the drug discovery arena. Special materials must be used in the construction of pumps for such applications before going in to use on Genevac evaporators. The pump is available in two sizes according to required flow rate; either 180 l/min and 90 l/min, both will reach down to 0.15mbar with ease. The larger unit is specified for Genevac’s new HT-24 Workstation for the large scale purification and synthesis sector and the Mega 980/1200, whilst the smaller unit is suitable for Genevac’s bench top evaporator models from DD-4 up to HT-12.

CENTRY® SUB ANSI CENTRIFUGAL PUMPS
Liquiflo's Centry line of Centrifugal pumps are available in 316 SS or Alloy-C with either Packing, Single Mechanical Seal, Double Mechanical Seal or Mag-Drive configuration.
Features
General:
Depending on the model, the Centry Series centrifugals are available as standard with closed impellers. Closed impellers eliminate axial loads and extend the life of the motor bearings when the pump is close-coupled to the motor. Closed impellers simplify the axial positioning of the impeller, when using close-coupled sealed pumps.
Single Mechanical Seals:
Single mechanical seals are the most economical type of seal to use when leakage is not desired. When properly installed and maintained, these seals will generally give years of trouble-free service.
Double Mechanical Seals:
Double Mechanical seals are also available for the Liquiflo Centry Series centrifugal pumps. This seal configuration relies on a barrier lubrication system to cool and lubricate the seal faces.
Magnetically-Coupled Pumps:
These offer a simple and cost-effective solution to sealing toxic, noxious, crystallizing or most other fluids that present problems for single seals and would therefore require use of a double mechanical seal. magnetically-coupled pumps eliminate the need for cooling loops that are required for double mechanical seals.

ENDURA® PUMPS
Liquiflo’s ENDURA® Pumps are Group I & Group II ANSI-Dimensional Magnetically-Coupled Seal-less Centrifugal Pumps. These pumps were designed to meet the demanding needs of the chemical processing
industry but will also handle many pumping applications, including those which require dry-running, pumping solids as well as high-temperature demands.
ENDURA® AB - Air Barrier
Liquiflo’s ENDURA® AB-Series is our Patented Air-Barrier Centrifugal Pump. This innovative revolutionary design was the recipient of the 1995 Vaaler Award. The ENDURA® AB can run dry indefinitely and handles solids - something no other pump in the industry can do.
The AB, (air-barrier) combines the best features of a standard sealed pump with that of a mag-drive pump, while eliminating the drawbacks commonly associated with these designs. This patented design makes the ENDURA® AB unlike any other pump in the industry.
How it works:
A gas seal isolates the process fluid from the bearings within a mag-drive pump. The benefit of this design is that the ENDURA® AB does not rely on the pumpage for lubrication. This allows the use of standard, greased-for-life ball bearings instead of the common sleeve bearings found in all other magnetically driven pumps.
Other Great Features:
• Can run dry indefinitely
• Lowest L3/D4 ratio of any pump - 9.3
• Solids handling up to 40%
• Close-coupled or power-frame
• ANSI dimensional for easy change-out
• Inherent secondary containment
• No seals to leak
