❶ Pump ID Meaning

❷ Test Procedure
Each pump manufactured by CRYOSTAR is mechanically and cryogenically tested prior to shipment in our state-of-the-art testing facility to ensure that performance meets customer specification. The precision of measuring devices provides essential results: differential head, flow rate, seal gas consumption, pump efficiency, NPSH, noise and vibration levels - all documented and submitted to the customer.
 

❸ Quality
Designed in compliance with guidelines like IGC 11/82 norm
 

❹ Features
1  Small mass of the suction chamber (faster/better cool down)
2  Large suction chamber volume
3  Direct degassing at the highest point of the cold end (further improved by a 45° slope of the discharge line)
4  Improved vacuum volume
5  Suction valve optimized to reduce pressure drops 
6  Optimized design and position of the vacuum connection
7  Waved line on the cylinder to avoid stresses resulting from cold contraction (extends cylinder life)
8  Increased number of piston rings for higher volumetric efficiency 
9  Optimized sealing and guidance of the monel piston
10 PT100 probe for seal leak detection
11 Open intermediate piece   no need for purge
12 Following features offer an extended lifetime :

• Crosshead guided by wear segments
• Sealing package with interchangeable cartridge => no need to disassemble entire crank drive
• Rigid and auto-centred coupling of the piston

13  Oil splash lubricated crank drive with autonomous lubricating system independent of rotating direction
PT100 probe for anti-cavitation and leak detection included in standard scope of supply.
 

❺ Options

• 2 different types of Low Pressure seals : set or adjustable through tightening
• PT100 probe for crank drive temperature control
• PT100 probe in gas return line for cool-down protection
• Low Pressure seals heater for cold standby periods over 3 hours
• Crank drive purge connection
