Manufacturing industries often face difficulties such as equipment breakdown, overheating, unscheduled maintenance, etc.
More often than not, they all stem from a primary reason: improper lubrication. So, adequate lubrication is critical for maintaining the operational efficiency of machinery and prolonging its lifespan.
Without it, components can wear down quickly, leading to costly repairs and downtime.
This is where grease pumps come into play.
In this guide, we’ll explore all the details and functionalities of a grease pump and how the proper pump can be an invaluable asset for your industry.
A grease pump is a mechanical device that pumps grease into the line and injectors to dispense grease on a moving mechanical component.
Generally, grease has a density lesser than water, which is about 700 kg/m³ to 950 kg/m³, depending on the formation of the grease structure.
That’s why a grease pump differs slightly from a regular hydraulic pump.
Heavy industries and manufacturing plants use grease pumps to lubricate their machinery.
There are a lot of designs and types of grease pumps to choose from.
Different types of industries choose grease pumps according to their need.
Also, the types of grease used (NLGI value) affect the selection of various grease pumps.
Many grease pumps are available in the market, and they have various designs according to their need and working principles. In this section, we’ll discuss the general model of a grease pump and the working process of the model.
Now, before diving into the working technique, let’s learn about the main parts of a grease pump:
Let’s discuss the construction of a general grease pump while we’re at it.
The oil storage cylinder is the central part that stores grease and a pumping piston.
The cylinder outlet has a one-way valve to orient grease flow and prevent backflow.
An oiling or grease gun is installed at the rear end of the one-way valve.
Some extra components also sit at the top of the cylinder: the Air Pump, the Plunger Pump, and the air distribution chamber.
As we know, a piston consists of two pumps and an air-distributing chamber. When compressed air enters the air-distributing chamber, it activates the air pump. The plunger pump moves like a reciprocating pump, and it allows the air to enter and exit the chamber through valves.
Also, when the pump moves backwards, it creates a vacuum inside the chamber, allowing the grease to enter the pump. After that, the pistons’ forward motion pushes the grease to the one-way valve with high pressure. That one-way valve ends in an oiling gun. The gun dispenses grease to a desired location.
When it comes to machine lubrication, oil and grease rule the industries. Both have their strengths and weaknesses. But grease gives you some advantages that oil can’t.
The following parts of the machinery uses the grease for lubrication:
There are a lot of industrial categories which use grease for lubrication. From a broad perspective, the manufacturing and automotive industry uses this lube system the most, where metal parts collide and produce a lot of heat energy.
Wear and tear are common without or with an old lubricant, so a continuous grease supply is necessary for those moving parts. Only a grease pump can supply a regular amount to the machinery. These are some of the major industries where grease pumps can be used:
Those industries are enormous and deal with tons of metallic components. So, adopting the best grease pump is crucial for them.
Grease pumps are a prime element for the manufacturing industry.
Proper lubrication of machinery ensures its durability and highest performance.
So, grease pumps can be an excellent choice for the manufacturing industry.
These pumps are intended to manage friction while enhancing the machines’ durability, which helps reduce their operating cost.
Grease pumps feed automated lubrication systems with grease that allows a fixed amount to be applied to the instruments.
It’s a continuous process that reduces the need for manual greasing.
This process helps the manufacturing industry to save labour costs.
Also, this helps enhance the machines’ performance by delivering only the necessary amount of lubricant to the complicated pieces.
Furthermore, manufacturing machines work with heavy loads, pressure, and speed.
So manual greasing can be insufficient and dangerous at times.
However, a grease pump empowers the auto-greasing system to dispense grease while the production runs.
So, the ultimate goal of Grease Pumps is to enhance the durability of industrial processes by maintaining competency.
From the previous discussion, we have gathered an idea about the uses and importance of grease pumps.
To sum it up, grease pumps have some significant qualities that make them appear to be an integral part of machinery lubrication.
A grease pump is a necessary component for delivering the right amount of grease to the desired moving mechanical components.
Besides providing the grease, it has other important work in industrial plants and machinery. Let’s go through the following steps to find out all the functions of a grease pump.
There are many types of grease pumps with different working principles.
The most common types are manual grease pumps, air-pressured grease pumps and electric grease pumps. Grease pump features vary with the design, but the following are the most common features of a grease pump:
Every industrial sector depends on grease pumps. Industries rely on machines, and machines need proper functions to produce the highest output.
So, there’s no doubt that machines need adequate lubrication to function effectively.
Grease pumps lubricate machines to maintain their outstanding performance.
Let’s learn more about the versatile applications of Grease Pumps in various sectors-
Many manufacturers design and sell grease pumps according to the customers’ specific needs. Nowadays, some premade designs are available in the market. Those types are:
We can divide the components of the grease pump into two sections: one is the general component, and the other is the specific component.
All the general components fit in every type of grease pump, but they are not the same for all components.
System specific components only fit into their own type.
General components that are fit for most of the grease pump are:
These components don’t fit into every type of pump and only work with its compatible pump type. Here, we have discussed those components according to the pump type.
There’s no doubt that using grease pumps delivers an array of advantages. Let’s learn about some key benefits of grease pumps-
Despite having many advantages, there are still some flaws that can create concerns. Some main disadvantages are-
Given certain circumstances, grease pumps need various types of certification to ensure quality and safety.
Especially in food processing industries, some safety measures need to be followed intensively. Here are some main certifications mentioned for grease pumps-
These certifications ensure the users about the safety and reliability of the grease pumps and the lubricants.
The grease pump’s quality standards vary from country to country. Thus, standards depend on the actual application of equipment, industrial standards, and weather quality. Let’s learn about the quality standards of some countries:
Grease pumps are widely used in the industrial area. Also, working conditions always differ from industry to industry. You must maintain the following conditions while using the grease pump:
The service lifetime of a grease pump depends on the maintenance, working condition, and type of grease pump. Component or part lifetime will automatically increase if you can meet the decisive parameters. Pneumatic grease pumps give the most life compared to the other grease pumps.
Nevertheless, remember to clean the piston every 10,000 operations for a longer lifetime. Environmental and frequent use also affect on the lifetime. Exposed to the harsh environmental conditions and longer work shifts without any rest costs the pump’s lifetime.
So, the best advice will be to stick to your manufacturer’s guide. Strictly follow the do’s and dont’s for the most prolonged service life.
Different countries have their own standard for supplying electricity at a different voltages.
Industries have their own choice to use AC or DC supply, depending on their flexibility.
The good news is that the company produces pumps with various configurations and different types and values of electric supply.
Voltage Option: Most companies have the option to choose electric inputs like 24V DC, 115V AC, and 230V AC. For example, the HYKG Progressive Pump has the option of DC 24V/12V and AC 230V. The model HYE7X Single Line Pump has the following options: DC 24V/12V and AC 90V-230V.
Power Adjustment: This option is only available in the eclectic grease pumps. The pump’s power can be adjusted according to the pump’s output types. The pump will draw more energy while working under a high load and less in low-load conditions.
