With options for manual (MA), hydraulic (HS), and electric (EP) control, our PV series pumps give you precise control over direction, flow, and power output. They’re ideal for tough environments and are the top choice for professionals across various industries, powering everything from rollers and pavers to soil stabilizers, concrete mixers, and even pharmaceutical equipment.
Typical Applications
- Construction Machinery: Rollers, pavers, and soil stabilizers,
- Concrete Equipment: Self-loading concrete mixers
- Pharmaceutical Machinery: Where clean and efficient hydraulic systems are required for specialized operations.
Features
- Variable Swash Plate Design: Designed as a swash plate variable pump, primarily for closed-circuit drive systems, with output flow and direction changing according to the swash plate angle.
- Versatile Control Options: Control options include manual servo, electric proportional servo, and hydraulic servo, with modular valve replacement for flexibility.
- Easy Installation: The pump's installation interface meets international standards, making it easy to install and operate.
- Full Compatibility: Fully compatible with SUNDSTRAND PV20 series products for direct interchangeability.
- High-Pressure Capacity: Rated pressure reaches up to 42 MPa, meeting high-pressure application needs.
- Customized Solutions: Customized solutions are available based on your specific requirements.
