1. Graco Husky pump: models, applications and how to choose the ideal one for your industry
In the current context of innovation and high performance, understanding the applications of bomba graco husky: what applications is it ideal for? is fundamental. The Husky line brings together pumps of different sizes, capacities and construction materials. Depending on the model and configuration chosen, it is possible to work with different flows, pressures, viscosities and fluid characteristics.
But which model to choose? And for what applications is the Graco Husky pump recommended?
In this article, we will present the main characteristics of the technology, some models in the Husky line and the factors that must be evaluated before specification.
What is a Graco Husky pump?
Husky is a family of pneumatic double diaphragm (AODD – Air-Operated Double Diaphragm) pumps. The equipment uses compressed air as a drive source to move the diaphragms and transfer the fluid.
An important feature of this system is the absence of a conventional mechanical seal in direct contact with the fluid, which can be advantageous in certain transfer applications.
The Husky line has models with different connection sizes and materials for the wetted parts, allowing the equipment to be configured according to the characteristics of the pumped product.
According to Graco, the Husky family can reach 1,135 L/min (300 gpm) of flow, with models that have connections from 1/4″ to 3″, depending on the version.
How does a double diaphragm pneumatic pump work?
The operating principle is relatively simple.
The pump has two diaphragms connected by a shaft. Compressed air is directed alternately to each side of the pneumatic system, causing one diaphragm to advance while the other returns.
This movement creates suction and discharge cycles that allow the fluid to be transported.
The process is repeated continuously, pumping the product.
As the activation is carried out by compressed air, the technology may be interesting for installations in which the use of electrical equipment directly at the pumping point is not desirable or in which there is already a compressed air network available.

Liquids with certain concentrations of suspended solids.
However, it is not correct to choose a pump solely based on the type of fluid.
The same product may require different settings depending on its viscosity, temperature, concentration, abrasiveness and chemical composition.
Therefore, the chemical compatibility between the fluid and the wetted components of the pump is one of the main points of the specification.
The importance of construction materials
One of the differentiators of the Husky line is the availability of different materials to meet the characteristics of each application.
Materials that may appear in different configurations include aluminum, stainless steel, polypropylene, PVDF and other specific materials, depending on the model and configuration.
It is also necessary to correctly select components such as:
☑️ Diaphragms;
☑️Spheres;
☑️ Headquarters;
☑️O-rings;
Body and parts in contact with the fluid.
Incorrect selection of these components may result in premature wear, loss of performance or chemical incompatibility.
Therefore, the specification must be made considering the fluid and the real operating conditions, and not just the desired flow rate.
4. How to choose the right Graco Husky pump?
Before defining a model, some data is essential.
- What is the fluid?
Provide the commercial name and, when possible, the chemical composition of the product.
- What is the viscosity?
Viscosity directly influences the pumping capacity and flow obtained in the application.
- What flow is needed?
Define how many liters per minute the process needs to transfer.
- What is the discharge pressure?
The pump must be specified considering the pressure required at the discharge point, and not just the flow rate.
- What is the temperature of the product?
High or very low temperatures can alter fluid properties and material compatibility.
- Are there solids in suspension?
If the product contains particles, it is important to know the size and concentration of the solids. The different Husky pumps have different capacities for passing solids. For example, Graco documentation indicates approximately 3.2 mm for the Husky 1050, 4.8 mm for the 1590, 6.3 mm for the 2150, and 13 mm for the 3300.
- What is the availability of compressed air?
As the pump is pneumatic, it is necessary to evaluate the pressure and capacity of the available compressed air network.
Why rely on a company specialized in specification?
The choice of an industrial pump should not be based solely on the size of the connection or the maximum flow indicated in the catalogue.
An adequate specification considers the entire application set: fluid + flow + pressure + temperature + viscosity + solids + materials + installation conditions.
An oversized pump can result in unnecessary compressed air consumption and higher operating costs. Undersized equipment may not meet the process demands.
Therefore, having professionals who know pumping technology helps you find a suitable configuration for each need.
