Ideal
for transport of powder detergents, screw compressors are designed and
formulated to handle comprehensive range of dry material transfer
applications, such as granulates, sand, plastics, flour, cement, lime and
silicate.Models Available
Screw compressors are available in three designs, which include -
- Single and Two Stage - Single stage models have proved to be suitable
for uses on low to moderate compression ration applications. The two
stage models are suitable for superior compression ratio requirements.
- Air Cooled and Liquid Cooled - The air cooled models are suitable
for majority of PD pumps, which do not use gearboxes, especially for
operation and functioning at liquefied gas transfer and the lower
compression ratio applications. The liquid cooled screw compressors have
a liquid cooled head and a cylinder, which is especially designed for
more demanding applications.
- Single, Double and Triple Seal - The standard double-seal models of screw compressors are designed with a single distance piece between two piston rod seal sets. The distance piece ensures control of leakage control and prevents the oil contamination of the compressed gas stream. Triple-seal models are fitted with two distance pieces for optimum leakage control and are ideal for handling toxic, corrosive or hazardous gases.
- Heavy duty ductile iron construction
- One-piece piston
- Single and double distance pieces
- Heavy-duty precision ground crankshaft
- Live loaded piston rod seals
- High efficiency valves
Some of the important features and benefits of screw compressors include -
- High rate of flow
- Frictionless screw
- Clean, oil-free and air supplied construction that does not wear with time
- Requires minimum maintenance
