Kanayama Lubricators – Detailed Product Introduction

Kanayama Precision Co., Ltd. is a Japanese manufacturer that specializes in lubricators—devices that automatically supply lubrication oil to engines, compressors, and industrial machinery. Their lubricators are especially essential in marine engines and manufacturing equipment, ensuring constant oil supply to reduce wear, improve operational efficiency, and prolong equipment lifespan.

Kanayama supports not only manufacturing and sales but also maintenance and overhaul services for their lubricators and related systems. Their product lineup includes low‑pressure and high‑pressure variants, sealed and open-type configurations, and a range of accessory components.

Types of Lubricators

1. Low‑Pressure, Open Type Lubricators

Designed for applications with minimal pressure demands. These are easier to install and maintain where sealing is not critical.

2. Low‑Pressure, Sealed Type Lubricators

These feature enclosed systems to prevent oil leakage and contamination, suitable for many standard industrial applications.

3. High‑Pressure, Sealed Type Lubricators

Designed for heavy-duty engines and high-load equipment that require reliable oil supply under pressure.

4. Related Components

• Pump Elements (ML / MM series)

• Check Valves (for both low and high pressure)

• Flow Sensors

• Flow Alarms

• Oil Signal Indicators

• Distributors

PER‑8B – Low‑Pressure Sealed Lubricator (Oil Injector)

PER‑8B is a low‑pressure sealed type lubricator designed for automatic oil supply in industrial lubrication systems. It features a sealed self‑feeding lubrication tank that enables smooth automatic replenishment when connected to an elevated oil reservoir, eliminating frequent manual refilling and reducing the risk of lubricant shortages.

Key Specifications

• Type: Low‑pressure sealed lubricator

• Discharge Pressure: Up to approximately 7.84 MPa

• Oil Delivery per Stroke:

  • φ7 plunger: 0.06 – 0.36 cc per stroke

  • φ5 plunger: 0.03 – 0.19 cc per stroke

  • φ3 plunger: 0.01 – 0.07 cc per stroke

• Element Installation: 1 to 24 elements

• Oil Supply Method: Self‑feeding type

Features

Sealed Self‑Feeding Design
The lubricator tank is completely sealed, preventing leakage and contamination. By connecting a single pipe from a higher oil reservoir to the lubricator, oil is automatically supplied to the system without manual topping‑up.

Prevents Refill Forgetfulness
Automatic replenishment significantly reduces the risk of accidental lubricant shortage and removes the need for frequent manual refill tasks.

Simple yet Reliable Structure
The sealed construction is straightforward yet robust, ensuring long‑term reliability in industrial environments.

Easy Air Venting
The lubricator includes a simple air release valve that must be used only once during initial installation, simplifying setup and maintenance.

Typical Applications

The PER‑8B lubricator is suitable for use in various industrial lubrication scenarios, including:

• Diesel engine lubrication systems

• Film manufacturing tenter frame lubrication

• Large compressors

• Mid‑load bearings in kneaders and rolling mills

These applications benefit from continuous, automatic lubrication that ensures smooth operation and helps prevent wear, overheating, and premature failure.

Summary of PER‑8B Advantages

Conclusion

The PER‑8B low‑pressure sealed lubricator from Kanayama Precision Co., Ltd. is an efficient and reliable automatic oil injector designed for demanding industrial lubrication needs. Its sealed, self‑feeding design eliminates manual refill work and reduces lubricant supply failures, making it well‑suited for engines, compressors, and various industrial machinery.
