SULZER Oil Cup Assembly – Bearing Housing Lubrication Monitoring

About Dongguan HydroBlue Co., Ltd.

DONGGUAN HydroBlue CO.,LTD. is an engineering-based provider of high-quality pump replacement components to the global industrial fluid handling market — structured around the understanding that dependable pump operation begins with correctly specified, precisely manufactured parts at every level of the assembly.

Our technical team of 8 engineers and technicians integrates knowledge across the critical disciplines for pump engineering: hydraulic system design, mechanical design and precision machining, power electronics, and electronic measurement and control. This cross-functional capability allows us to evaluate each part request in the context of the operating system rather than processing it as an isolated transaction.

Our research collaborations expand our technical foundation:

  • Jiangsu University National Research Center of Pumps — hydraulic performance simulation and pump system analysis
  • Chinese Academy of Sciences — advanced protective coatings for pump components
  • Guangdong University of Technology — industrial automation and variable frequency drive systems

OUR BRANDS & SERVICES

Our proprietary brand delivers fully integrated fluid machinery solutions under a single point of accountability — combining parts supply, system engineering, and international field services. The product portfolio includes pumps, frequency converters, servo drives, PLC-HMI controllers, motor control cabinets, electric motors and gear reducers, mechanical seals and assemblies, couplings, and gearboxes. Field engineering services include overseas FARO 3D scanning, laser alignment, pump commissioning, and on-site debugging by our own engineers.

Product Overview

SULZER Oil Sight Glass & Oil Cup Assembly is a bearing-housing-mounted visual indicator that allows operators and maintenance personnel to verify the oil level in the bearing housing without opening the pump. It typically consists of a transparent sight glass (borosilicate glass tube or acrylic prism), a metal or polymer body that threads into the bearing housing wall, sealing O-rings or gaskets, and a protective cage or shroud in some configurations. Some designs include a spring-loaded oil cup that maintains a constant oil level by allowing excess oil to return to the housing while keeping the sight glass filled at the correct level.

The oil cup may also serve as a filling port for adding oil to the bearing housing without disassembly. In pumps operating in outdoor or washdown environments, the sight glass allows quick visual confirmation that the oil level is correct before start-up and during routine inspection rounds.

Our replacement oil sight glasses and cup assemblies are manufactured to match the original SULZER bearing housing thread pattern, mounting dimensions, and seal profile.

Installation & Maintenance Tips
  • Thread Sealant — Apply PTFE tape or thread sealant to the body threads before installation; do not overtighten — excessive torque may crack the sight glass or distort the seal
  • Orientation — The sight glass should be positioned at the specified oil level height; the oil cup fill line should align with the housing's normal oil operating level
  • Cleaning — Clean the sight glass periodically with a soft cloth; avoid abrasive cleaners that can scratch the glass or polymer surface
  • Crack Detection — Inspect the sight glass for cracks or fogging during each routine inspection; replace immediately if damaged to prevent oil loss
  • O-Ring Replacement — Always replace the sealing O-ring when changing the sight glass assembly to ensure a leak-free seal
