PUMPING UNITS

Product catalog summary

Overview: This document is a reference guide detailing the compatibility between various pumping units and compressor frames, focusing on models such as MCH 6, MCH 7, MCH 8/9, MCH 16, MCH 21, MCH 22, MCH 36, MCH 5 CNG, MCH 10/14 CNG, and MCH 20 CNG. It includes specifications, components, and compatibility information for each model.

Specifications: Each pumping unit is described with detailed specifications including charging rate, maximum working pressure, speed in RPM, number of stages and cylinders, cylinder bore sizes, stroke length, direction of rotation, drive type, oil amount, and intake pressure. For instance, the MCH 6 model has a charging rate of 100 l/min, a maximum working pressure of 330 bar, and operates at 2,500 RPM with four stages and cylinders.

Components and Features: Common components across models include lubrication systems (splash or forced), suction filters, stainless steel pipes and fittings, forged aluminum connecting rods, forged steel crankshafts, safety valves, and CE certification. Some models also feature intermediate condensate separators, synthetic oil formulations, and special cast iron cylinders.

Compatibility: The guide provides a list of compatible compressors for each pumping unit, ensuring optimal performance by matching the correct compressor frame with the pumping unit.

Recommendations: Emphasizes the importance of using specified components and adhering to operational parameters to maintain efficiency and safety. It also advises on proper installation practices, such as avoiding filters and condensate separators for certain models.

Performance Parameters: Performance is measured by the charging rate during a 10-liter cylinder filling from 0-200 bar, with a tolerance of +/- 5% at 20°C ambient temperature. Specifications include minimum and maximum values for liters per minute (l/min), cubic meters per hour (m3/h), and cubic feet per minute (cfm).

Materials and Construction: Units feature special cast iron cylinders with low roughness lapping, die-cast aluminum cylinders with nicasil coating, and stainless steel valves, designed to handle high pressures and intensive workloads.

Applications: The boosters are suitable for various applications including firefighting, paintball/PCP, racing, diving, and industrial uses.
