PVH098 VICKERS variable piston pump

PVH098 VICKERS Variable Piston Pump Specifications

1. Basic Specifications

  • Pump Type: Variable Displacement Inline Piston Pump
  • Application: Industrial and Mobile Equipment (earthmoving, construction, machine tools, plastic machinery, etc.)
  • Design Feature: Compact size, light weight, high power density, low noise (optional QI type for industrial low-noise design)
  • Volume Efficiency: ≥94% – 96%

2. Performance Parameters

  • Maximum Geometric Displacement: 98.3 cm³/r (6.0 in³/r)
  • Maximum Operating Pressure: 250 bar (3625 psi) for continuous duty; 280 bar (4050 psi) for load sensing systems
  • Speed Range:
    • Industrial Type (QI): Maximum 1800 rpm; Output Flow: 170 LPM (45 GPM) @ 1800 rpm
    • Mobile Type (C): Maximum 2100 rpm; Output Flow: 181 LPM (48 GPM) @ 2100 rpm
    • Note: Speeds at 10% displacement need to be reduced to rated speeds at 100% displacement
  • Fluid Requirement: Petroleum-based hydraulic oil; Viscosity: 32 cSt at 38°C (150 SUS at 100°F); Inlet Pressure: 0 psi (standard)
  • Oil Temperature Range: Suitable for normal industrial and mobile operating temperature (specific range subject to actual application)
  • Noise Level: Low-noise design available for noise-sensitive industrial applications

3. Installation & Structural Parameters

  • Mounting Flange: SAE “C” 4-bolt type (SAE J744-127-4); Optional ISO 3019/2–125B4HW (not applicable for PVH098)
  • Shaft Rotation: Clockwise (R) or Counterclockwise (L) when viewed from the prime mover end
  • Shaft Extension Type:
    • Options: Short straight keyed shaft, SAE “C” splined shaft (14 tooth/17 tooth), SAE “CC”/”D” splined or keyed shaft
    • Example: 31.8 (1.25) dia straight keyed shaft with 56.0 (2.20) shaft extension
  • Shaft Seal: Single one-way (S) or double two-way (D) fluorocarbon seal; Double seal recommended for series units and wet mounting
  • Main Ports:
    • Suction Port: 2.500 SAE 4-bolt split flange port (Code 61) with 1/2-13 UNC-2B threads
    • Pressure Port: 1.000 SAE 4-bolt split flange port (Code 61) with 3/8-16 UNC-2B threads
    • Drain Port: 0.875-14 UNF-2B SAE O-ring port (bottom, top plugged)
  • Operating Weight: 108 lbs (49 kg)

4. Control & Other Parameters

  • Control Modes (Optional):
    • Pressure Compensator (C/CM/IC): Adjustment range C: 70-250 bar (1015-3625 psi); CM: 40-130 bar (580-1885 psi)
    • Load Sensing (V): 20 bar (290 psi) pressure difference setting
    • Torque Limiter (T): Factory settings in 10 bar (145 psi) increments; Custom settings available
    • Combined Controls: Load Sensing + Pressure Compensator (CV), Load Sensing + Torque Limiter (VT)
  • Pressure Compensator Factory Setting: 250 bar (3625 psi) for C type (coded as 25)
  • Oil Cleanliness Requirement: ISO 16/14/12 or cleaner for extended component service life
  • Design Number: 10 (installation connection dimensions remain unchanged for design numbers 10-19)
  • Special Options: Adjustable maximum displacement stop (S, only for non-through drive and non-torque control models); Composite 2-bolt/4-bolt mounting (027); Vertical installation (057)
