Product Overview
▔▔The Parker T7 Series High Pressure Fixed Displacement Hydraulic Vane Pumps (formerly Denison Hydraulics T7 Series) are industry-leading hydraulic pumps engineered specifically for heavy-duty industrial and mobile applications requiring high pressure, superior efficiency, and reliable long-term performance.
Key Advantages
▔▔-
Extreme Pressure Capability: Operates reliably at continuous working pressures up to 300–320 bar (4,350–4,650 psi), significantly outperforming conventional vane pumps.
Double-Lip Pin-Vane Technology: Reduces vane tip loading on the cam ring, minimizes internal leakage, and extends cam ring and shaft service life.
Exceptional Volumetric Efficiency: Maintains over 94–96% volumetric efficiency across its operational cycle, drastically reducing energy losses and fluid heating.
Ultra-Low Noise Levels: Ideal for noise-sensitive industrial environments, operating at sound levels as low as 62–68 dB(A).
Flexible Cartridge Design: The drop-in replaceable cartridge concept allows fast displacement changes, field servicing, and overhaul without removing the pump housing from fluid lines.
Multi-Pump Configuration Flexibility: Available in single, double, and triple pump variants driven by a single input shaft to power multiple independent hydraulic circuits.
Broad Fluid Compatibility: Compatible with standard mineral oils, synthetic fluids, and fire-resistant hydraulic fluids (HFC, HFD) when paired with suitable seal configurations.

FAQ
▔▔Q1: What makes Parker T7 pumps different from standard hydraulic vane pumps?
Answer: Traditional vane pumps are generally limited to maximum operating pressures between 175 and 210 bar. The Parker T7 series utilizes specialized double-lip pin-vane technology and hydraulically balanced internal geometry, allowing it to sustain continuous working pressures up to 300 to 320 bar (4,350 to 4,650 psi) while maintaining extremely low noise and high volumetric efficiency.
Q2: How does the replacement cartridge design benefit field maintenance?
Answer: The Parker T7 pump is designed around a removable cartridge kit containing the cam ring, rotor, vanes, side plates, and bearings. If a pump suffers wear or if system flow demands change, maintenance personnel can simply open the pump endcover and swap the cartridge kit without removing the main pump housing from the machine mounting flange or disconnecting hydraulic hoses. This reduces machinery downtime from hours to minutes.
