A1: Key parameters vary by model but follow consistent series standards :
- Deslocamento: JRRS45 (45 cm³/r), JRRS51 (51 cm³/r), JRRS60 (60 cm³/r), JRRS75 (75 cm³/r)
- Classificação de pressão: Pressão de trabalho contínua até 310 bar (4495 psi); pressão de pico 400 bar (5800 psi)
- Faixa de velocidade: Minimum stable speed 500 RPM; velocidade máxima 2800-3360 RPM (varia de acordo com o modelo)
- Fluxo Teórico: Até 126 L/min (JRRS45) para 180 L/min (JRRS75) at nominal speed
- Peso: Aproximadamente 40 kg per unit (peso líquido) .
A2: The series boasts 3 key structural advantages :
- Design Type: Axial piston variable displacement structure with 9 reciprocating pistons and a servo-controlled swashplate
- Material & Durabilidade: Polymer-coated smooth bearings for the swashplate; high-strength alloy pump body with wear-resistant internal components
- Installation Flexibility: Standard SAE B/C flange connections (2/4 parafusos) and multiple shaft options, enabling easy integration with diverse machinery .
A3: They are widely used in 2 major sectors :
- Core Machinery: Construction equipment (escavadeiras, pavimentação, rollers, escavadeiras), maquinaria industrial (equipamento metalúrgico, estações hidráulicas), and concrete pumps/mixers
- Compatibilidade do sistema: Optimized for open-circuit hydraulic systems; supports multi-circuit power transmission for complex machinery operations.
A4: Control and customization cover 3 key aspects :
- Standard Controls: Pressure-compensated control and load-sensing control (específico do modelo: por exemplo, “computador” control code for JRRS45BPC28…)
- Displacement Adjustment: Equipped with an adjustable displacement limiter (FFF code) para 0-100% flow regulation
- Optional Features: Customizable pressure settings (por exemplo, 250 bar preset for some models), configurações de eixo, and mounting orientations.
A5: Comprehensive support includes :
- Garantia: 1-year manufacturer’s warranty for defects (covers parts and labor)
- Serviços: Online technical consultation, maintenance guidance, and quick supply of repair kits
- Embalagem & Entrega: Export-standard wooden box packaging; lead time 15-30 dias (stock availability reduces delivery to 7-10 dias)
- Payment Terms: Flexible options (L/C, T/T, Western Union) with MOQ of 1 unidade.
A6: The specific model code indicates tailored configurations :
- “computador”: Pressure-compensated control mode
- “28”: Preset pressure setting (280 bar)
- “FFF”: Adjustable full-range displacement limiter
- “C2NV”: Shaft type and seal configuration for harsh working environments
- Compatibilidade: Direct interchangeable with Sauer Danfoss original models (por exemplo, número da peça 83047580).
