DR Series Electric Oil/Grease Lubrication Pump (GEAR TYPE)

Short Description:

Description
DR Series electric lubrication pump is a gear pump, reasonable structure,excellent performance, wide range of application,the self-priming performance is strong, high volumetric efficiency,can use lubricating oil with viscosity between 20~2000cst. Its oil tank volume has three specifications of 3 liters and 4 liters. 6 liters, 4 liters .The pump has a level switch. According to different uses, pressure switch can also be configured, connected to the programmer on the pump. It can also be connected to the user’s main device program controller system,Can achieve the oil level in the oil tank,oil pressure monitoring system,as well as the equipment lubrication cycle.
DR Series electric lubricating pumps can form a PDI lubrication system with a quantitative oil injector (PDI) to perform quantitative oil injection lubrication on each lubrication point; it can also form an SLR lubrication system with a metering part (MU) to perform proportional oil lubrication on each lubrication point;
DR series of electric lubrication pumps can be widely used in the centralized lubrication system of various equipment such as machine tools, plastic machinery, textile machinery, light industry machinery, printing machinery, escalators and transportation machinery.

Performance and features
The rated working pressure is 2.0Mpa/4.0Mpa, and there is a relief valve to prevent the oil pump from overloading.
It has unloading function: After stopping work, can remove the oil pressure in the main pipe of the system and it is mainly used in the Quantitative type (pressure or unload pressure type ) concentrated oil centralized lubrication pump.
With liquid level switch (normally open AC220V/2A DC36V/2A), used to detect the main oil pipeline disconnection and loss of pressure in the lubrication system (optional)
The pump can be with a PC-2 digital display controller to control the running time and rest time. (optional)
Transparent resin tank
Use oil:32-1300cst Use grease oil: 000#,00#,0# Lithium grease
Matching distributor: pressurized or unloaded distributor..

Notice
The pressure switch should be installed at the end of the system main pipe instead of being installed in the oil pump, so can more accurately monitored the current interruption and the pressure loss of the main circuit of the lubrication system

2.If the host itself does not have a PLC or has a PLC but the wiring is inconvenient, the oil pump should be equipped with a controller , The controller controls the duty cycle of the lubrication pump in a countdown mode: run time and rest time

3.If the power is not AC380V, 50HZ, When order should be indicate the specific work power
4.The following table shows the specific technical parameters for DR series oil pump ( without pressure switch and controller as an example). The technical parameters are the same with pressure switch or controller.
DR5-34 : Standard Flow 0.50L/min ,Oil Volume 3.0L,Standard Pressure 2.0Mpa ,Voltage AC380V,50HZ ,without pressure switch ,without controller
DR5-34P : P Mean with pressure switch
DR5-34C:C Mean with controller
DR5-34CII: C Mean with controller ,It mean Voltage AC220V
If the working power requirement is special, the voltage and frequency should be indicated when ordering .

DR5-34Z : Standard Flow 0.50L/min ,Oil Volume 3.0L,Standard Pressure 4.0Mpa ,Voltage AC380V,50HZ ,without pressure switch ,without controller
DR5-34PZ : P Mean with pressure switch
DR5-34CZ:C Mean with controller
DR5-34CZII:C Mean with controller ,II mean Voltage AC220V
If the working power requirement is special, the voltage and frequency should be indicated when ordering for example : DR5-32/460V60HZ
