SPB VTP - High Speed V-Belt Pulleys

SPB High Speed VTP (Ventilated Turbo Pulley) V-belt pulleys are special V-belt pulleys. They are made of cast iron GGG 50.

Compared to common gray cast iron pulleys, they have significantly better properties, higher strength and durability, lower weight, higher peripheral speed.

The pulleys are mounted to the shafts using the Taper bushes.

Pulleys Fields of Use

The VTP® V-belt pulleys are designed for the highest peripheral speeds in all areas of engineering, especially for applications with high temperature, alternating and impact load, and wherever the conventional cast iron V-belt pulleys cannot be used.

They are typically used in compressors, blowers, machine tools, in the paper and chemical industry and in many other machines.

Pulleys Characteristics

  • Up to 50% lower weight
  • Increased peripheral speed up to 60 m/s (theoretically up to 100 m/s)
  • Lower moments of innertia
  • Longer V-belt life-span
  • Made of cast iron quality GGG 50 of higher strenght
  • New CDP (KTL) coating improves rust protection
  • Decreased temperature of the belts - up to 17 °C

Pulleys Material

Cast iron GGG 50.

Pulleys Advantages

Pulleys Advantages

Decreased temperature of the belts up to 17 °C

A study demonstrates reduction of temperature of belts in VTP® pulleys up to 10 to 17 °C against standard pulleys. The pulleys have a perforated bottom groove and the heat is drained off the belt better during operation. Punching does not affect the pulley strength.

Belt Temperature Graph - Standard Pulley vs. VTP Pulley

The tests show that the belts after 2 hours of operation of the VTP® SPB250-4 pulley have a temperature more than 10 °C lower that the standard SPB250-4 pulley.

Belt Temperature - Standard Pulley after approx. 2 hours of operation Belt Temperature - VTP Pulley after approx. 2 hours of operation
