Lovejoy offers a variety of designs and models in its gear coupling family. From standard, off-the-shelf stock to new, high speed, special designs, Lovejoy can satisfy your gear coupling needs. The original Continuous Sleeve, or “C” coupling, offers a lightweight, compact, and simple design without compromising torque carrying capacity. The Flanged Sleeve, or “F” coupling, is available in exposed or shrouded bolt styles in which the number of bolts, size of bolts, and bolt circle are identical with industry standards. The nylon sleeve gear couplings, Nyflex and Mite, are compact, lightweight couplings that use a nylon sleeve and two sintered iron hubs. Lubrication is not required with the nylon sleeve. Lovejoy also has an All Metal Labyrinth Seal coupling and an Alloy Steel coupling. The All Metal Labyrinth Seal coupling is a flanged sleeve style, but uses no elastomeric seals. The Alloy Steel coupling is made from AISI 4140 steel.

APPLICATION:
The type oil gear pump AD-L is ideally suited in single-line centralized lubrication systems. In these systems, lubricant is being delivered intermittently under pressure (pressurizing - and relief cycles) through the main feed lines towards the meter elements installed downflow and
from there through the lube lines to the points of application.
FUNCTION:
The oil lubricator basically consists of a gear pump with A.C. single-phase motor, the oil reservoir, the electronic control unit and a valve which ensures that the line is depressurized when the A.C. single-phase motor is switched off (relief cycle). An integral pressure relief valve is opened as soon as reaching a pressure of 2 MPa (20 bar) thus protecting the oil gear pump from damage in the event of an overpressure situation occuring. After relief the main line, the valve maintains a resudial pressure of approx. 0.08 MPa (0.8 bar) and thus prevents that the main line runs empty. The entire system is either time- or pulse controlled, at choice.
