  • Function

  • The SPD1 series of double pumps consists of two SP20B pump sections.
  • The SP20B pump utilizes self-lubricating thrust blocks that eliminate the
  • need for separate wear plates. They are made from a high strength aluminum
  • alloy with exceptional anti-galling properties. This new thrust block design also
  • incorporates advanced bearings designed specifically for high pressure hydraulic
  • pumps. This new bearing features a robust fluoropolymer PTFE wear surface
  • that yields unsurpassed load carrying capabilities and cavitation resistance
  • even at low speeds and moderate levels of contamination. Also, since the
  • PTFE resin layer is self-lubricating, contamination from bearing wear in high
  • load situations (when no oil film is present) is reduced. This new thrust block
  • design combined with these advanced bearing results in lower friction and less
  • internal oil loss resulting in higher pump efficiencies.
