Lubricators


Gerhardt Lubrication Pumps

The Gerhardt PE AD lubricating pump is an in-line, positive displacement, plunger-type unit capable of delivering accurate quantities of fluid under high pressure for both lubricating and process requirements. The pump is capable of delivering precisely metered amounts of fluid under a wide range of pressures and is especially suited for use with centralized lubricating systems.

The Gerhardt pump has been a mainstay in industrial applications, especially in pipeline and gas transmission compressors, as well as in industrial mixers used for compounding rubber and plastics.

T.F. Hudgins, Incorporated, is the exclusive source for Gerhardt lubricating pumps and provides all manufacturing, sales and support.

Versatility. The Gerhardt pump can be supplied in one, two, three or four cylinder versions. Each cylinder can deliver a different lubricant for either lube oil or process oil service. It can be driven from either the right or left hand side.

High Performance. The pump delivers precisely metered amounts of fluid and is capable of generating extreme high volumes and pressures.

Robust Construction. The pump housing is made of aircraft grade aluminum and all steel wear parts are hardened. The unit is ruggedly constructed for decades of reliable service.

Features & Benefits

  • Supplied with up to four cylinders
  • Each cylinder can deliver a different lubricant
  • High-volume, high-pressure operation
  • Durable construction
  • Complete repair and support services from T.F. Hudgins

Manzel® Box Lubricators

This is a standard Pump-to-Point system in which pumps mounted on a common reservoir dispense oil to a single lube point operated by individual cams on a camshaft.

Pumps. Manzel® box lubricators use model 88 and 76 pumps, which are available in three plunger sizes: 3/16 inch, 1/4 inch and 3/8 inch. Reservoir sizes range from 4 pints to 40 pints and accommodate up to 24 pumps. Pumps are available with electric heaters and thermostats, automatic fill, low level switches and shaft rotation alarms. Manzel® box lubricators are suitable for pressures up to 7,500 psi.

Drive Options. Options range from a 1:1 direct drive to a 400:1 high-ratio drive. Drives may be mounted on the left or right end of the reservoir, with both rotary or ratchet styles available. Motor packages may be custom-designed for your lubrication needs.

Durability. All working parts are totally enclosed and protected from dirt, water and impurities. Each moving part is self-lubricated at all times by the fluid in the reservoir.

Flexibility. Manzel® box lubricators are designed to easily interchange with other makes and models of lubricators used in petrochemical refineries, gas transmission plants, food processing mixers, lumber, rubber and other applications.

Features and Benefits

  • Cost-effective oil systems using standard components
  • Rugged construction for durability
  • Saves system design costs and decreases lead time 
  • Precise camshaft alignment insures accurate lubrication
  • Can be used outdoors in harsh environments such as ammonia and sour gas
  • Easy-to-service pumps can be added or replaced quickly
  • Pump output is easily adjustable

Manzel® Model 88 Pumps

The Model 88 pump is a heavy-duty precision metering pump capable of accurately pumping small flows of either mineral or synthetic oil to machinery injection points. The single-piston pump is mechanically driven from a camshaft in the reservoir and is adjustable from 1 to 27 drops per stroke, depending on the piston size.

Pressures. The pump can develop pressures up to 7,500 psi, depending on the piston size (3/16, 1/4 or 3/8 inch).

Applications. Model 88 pumps are designed for use in Manzel® Model 55 and 76 box lubricators, as well as Mega®, Lincoln® and Premier® Model 55 box lubricators. Output ranges vary slightly depending on the lubricator.

Durability. Model 88 pumps are rugged, heavyduty units that include a precision-machined steel sleeve fitted with an alloy steel piston. Pumps are actuated by a hardened steel roller-rocker arm following a cam for low wear and longer life. The visual sight glass is one-piece, injection-molded material that is impervious to ultraviolet rays and mineral and synthetic oils.

Features and Benefits

  • Rugged construction for durability
  • Suction and gravity/pressure feed models available
  • Hardened cam rollers increase pump life 
  • Pump output is easily adjustable
  • One-piece sight glass for fewer leak path and seal points
  • Replaces Premier®,Mega®, Lincoln® and McCord® pumps

Manzel® Model 76 Pumps

The Model 76 pump is a heavy-duty precision metering pump capable of accurately pumping small flows of either mineral or synthetic oil to machinery injection points. The single-piston pump is mechanically driven from a camshaft in the reservoir and is adjustable from 1 to 27 drops per stroke, depending on the piston size.

Pressures. The pump can develop pressures up to 7,500 psi, depending on the piston size (3/16, 1/4 or 3/8 inch).

Applications. Model 76 Pumps are designed for use in MBL lubricators with 1/2-inch rise cams.

Durability. A hardened steel roller-rocker arm following a cam actuates the pump and reduces torque. The round sight glass is one-piece, injection- molded material that is impervious to ultraviolet rays and mineral and synthetic oils.

Features and Benefits

  • Rugged construction for durability
  • Suction and gravity/pressure feed models available
  • Hardened cam rollers increase pump life
  • Pump output is easily adjustable
  • One-piece sight glass for fewer leak path and seal points

Manzel® Model High-Pressure Lubricators

Manzel® High-Pressure force feed lubricators have precision metering pumps operated by a single cam on a camshaft. They dispense lubricant from a rugged, cast-iron reservoir containing the lubricant to be dispensed.

Manzel® High-Pressure lubricators are specified by leading equipment builders in the chemical and petrochemical industries in the United States, Europe, Japan and South America.

Versatility. Manzel® High-Pressure lubricators are available with various drive arrangements to accommodate a broad range of lubricants, viscosities and required line pressures. Three pump options are available: HP-15, HP-50 and HP-60.

Easier Service & Operation. These "Dri-Vac" sealed units make it easier to remove pumps for service and replacement by eliminating the need to disassemble the complete lubricator assembly.

A single hand adjustment of the regulator knob regulates feed, from a fraction of a drop to full pump capacity.

Features and Benefits

  • Rugged construction for durability 
  • Operating pressures up to 60,000 psi
  • Pump output is easily adjustable
  • All working parts are enclosed and self-lubricated
  • Compatible with both mineral and synthetic-based lubricants
