Specification: 75/280/300 cc/rev Rated pressure: 350/370 bar Peak pressure: 400/420 bar
Designed for open loop concrete pump and
crane applications. Shorter pump suitable
for limit installation space. The HP3V-75S
series pump is capable of tandem pump
to work with other pumps. The developed
various controllers can meet requirements
of all kinds of applications.
• Higher working pressure, rated working pressure up to 350 bar. • Higher efficiency, improved by 2% ~ 3% than similar products. • Compact design to meet tight installation space requirements, optimized axial structure with 10% shorter total length than the last generation HP3V series. • Optimized port plate, lower noise. • Heavy-duty bearings and increased drive shaft dimension for higher load and longer life time. • Various controllers suitable for requirements of all kinds of applications.
