Pump Specifications
The document provides technical details for the PPC 35/26 and PPC 45/26 pump models. The numbers indicate the model type, piston diameter (in mm), and piston stroke (in mm). These pumps are used for cylinder filling applications and are capable of pumping liquids such as LCO2 and LN2O. The PPC 35/26 model has a design pressure of 120 bar (1740 PSI), while the PPC 45/26 model has a design pressure of 100 bar (1450 PSI).

Drive Type
The pumps utilize a grease-lubricated crank drive system.

Testing Procedures
Each pump undergoes mechanical and cryogenic testing at Cryostar's facility to ensure performance meets customer specifications. Key performance metrics include differential head, flow rate, seal gas consumption, pump efficiency, NPSH, noise, and vibration levels. These results are documented and provided to the customer.

Performance and Quality
The pumps are designed in compliance with guidelines such as the IGC 11/82 norm.

Features
1. The pumps feature a straight inflow suction valve for low resistance flow, ensuring a low NPSH requirement.
2. The piston is made of stainless steel for safer operation.
3. A conical type sealing is designed for CO2/N2O applications, accommodating higher suction pressures.
