Let’s start with vane pumps, devices that are generally used in cases when the operating pressure and flow rate are not very high or when the volumetric efficiency required at high pressures is not particularly elevated. They offer the advantage of being easy to handle, since it is quite a simple operation to change the displacement and create systems with single, double or triple pumps. For more than 20 years, Interfluid has been the unquestioned leader in this segment, being able to count on a time-consolidated experience, a well equipped workshop to ensure rapid order processing and shipment, a high level of assembly flexibility and an accurate quality control system.

The go-to brand is certainly Veljan, a company which has specialized in the construction of vane pumps since and has belonged to the Hagglunds and Denison Group for almost 30 years. The sound reliability and wide range of vane pumps Veljan offers make it one of the top producers on the international market. Interfluid stocks hundreds of hydraulic vane pumps and motors in the company warehouse and this enables us to ship most orders within a few days. All Veljan VT6 and VT7 pumps and their respective spare parts are perfectly compatible with Parker Denison.
To complete the range, Interfluid markets the pumps of the Atos series PFE and the Hydraut medium pressure vane pumps of the series HS, HQ and VH which are perfectly interchangeable with Vickers, spare parts comprised.
The differences between these brands in terms of range, that is to say size, displacement, operating pressure and interchangeability, enable Interfluid to offer customers an extremely wide range of solutions in terms of technical solutions and price.
A hydraulic hand pump is a simple, yet essential piece of equipment used in a variety of industries. They are vital for many force applications – especially in construction, manufacturing, and maintenance operations.
However, with so many different models on the market, it can be difficult to know which is best suited to your type of work. This guide will help you understand the different pump types and their features.
Before you go ahead and buy a hydraulic hand pump, it’s important to do your research and understand their differences. With so many to choose from, you will want to compare features and prices. It is also a good idea to assess the quality of the product and if it’s made by a reputable manufacturer.
A hydraulic hand pump does a simple job, which is to deliver pressurized hydraulic flow to a tool and then return it back to the pump reservoir. But that doesn’t mean you should take shortcuts and opt for the first one that appears in your internet search results. There are a few simple but important considerations to take on board that will steer you towards the right product.
When you are choosing a hydraulic hand pump, it is important to prioritize quality over price. A high-quality Enerpac pump will last longer and be more reliable than a cheaper model. You will save money in the long run as you won’t need to replace it for many years.
With each stroke of the handle on a single-speed hydraulic pump, hydraulic oil is drawn from the pump reservoir towards the tool by the same amount. For many applications, this simpler and lower-cost option is fine. But for projects needing greater flow, for example when oil is to be pumped to a large hydraulic cylinder (or multiple cylinders), a single-speed pump can be hard work.
The alternative is a 2 stage hydraulic pump (2 speed), which has the added advantage of delivering high flow at lower working pressures. This gets you faster to the point where the real work begins. It then automatically delivers low flow at high pressure just at the time when you need more control. Compared to a single-speed pump, some two-speed types can reduce the number of handle strokes by as much as 78%! For a more in-depth comparison read our other blog post.
Hydraulic hand pumps are available in a wide range of oil capacities. A small model typically has a usable capacity of around 20 in3 (327 cm3), but there are some with as much as 453 in3 ( cm3). A larger reservoir will give you more options but will obviously make the pump much heavier, so think about how much oil is really needed for the applications you intend to carry out.
Most Enerpac Hydraulic Hand Pumps can withstand pressures up to 10,000 psi (700 bar), but this isn’t always necessary. For lower working pressures up to 5,000 psi (350 bar) the P18 is a cost-effective single-speed option. However, if you need a 2 stage hydraulic pump go for the P.

When it comes to the materials used for the main body of the pump, you have the choice of steel or glass-filled nylon. There’s plenty of configurations available in both types, so it really comes down to your personal preferences, weight, and the working environment. Metal-bodied pumps are the traditional tried and tested option that offer reassurance to many people. However, glass-filled nylon reservoirs are also incredibly durable, and these offer an unrivalled combination of strength, weight, and resistance to corrosion. A glass-filled nylon pump will be a few pounds lighter than steel equivalents.
If you intend to use your pump with hydraulic cylinders, will these be single or double acting?
A double-acting cylinder gives you a faster and more controlled plunger retraction, but you will need a pump designed specifically for this purpose. Take a look at the P842, P84, and P464 models.
Safety should always be the number one concern, so choosing a good quality pump from a reputable manufacturer is an essential first step. Some features and tips relating to safety include;
• Non-conductive fiberglass handle
• Internal pressure relief valves for overload protection
• Lower handle effort of 2-stage pumps
• Handle lock and lightweight construction for easy carrying
• Corrosion-resistant finishes
• Using a pressure gauge as a ‘window’ to what’s going on within the system
• Always follow manufacturer operator instructions
• Consider extra safety tools such as the Hydraulic Coupler Bleed Tool for safe depressurization
• Make sure you keep threads on couplers clean and in good condition.
When working in extreme environments such as the oil & gas, or petrochemical industries, a hydraulic pump may be exposed to corrosive substances and extreme temperatures. For these situations consider pumps with corrosion-resistant materials such as stainless steel, nickel-plated valves and cylinders, anodization, and plastic-encapsulated metals. Viton® Seals will also offer heat and chemical resistance.
Foot Pumps
Would a foot pump suit you better? If crouching to activate your hand pump is an issue, or if you want to keep your hands free then a foot pump could be a good alternative option. Look at the P392FP which is a 2 stage foot pump with a robust steel frame.

Powered Pumps
For ad-hoc projects, a hand pump is likely to be the right choice. But for frequent and repetitive projects – and especially those with multiple cylinders a powered pump could be much better for you. Plug in electric and compressed air hydraulic pumps are common. For remote locations without mains power or a compressed airline the choices are battery and gasoline-driven pumps.
Battery Driven Hydraulic Pumps
If your work involves using hydraulic cylinders buying a cylinder and pump set is a quick and easy way to get what you need, without the hassle of buying components separately. A set typically includes a single-acting hydraulic cylinder (aka a jack or ram), a two-speed pump, a 6-foot hose, calibrated gauge, and a gauge adaptor. Cylinder capacities vary from 5 to 100 tons and the pump options include hand or foot-operated models.
Cylinder and Pump sets
Once you have chosen the right hydraulic hand pump, you’ll need to find a reputable supplier.
You can locate your nearest Enerpac distributor on our website. Or if you are based in the United States you can order your pump online directly from Enerpac.
Most people reading this article will be technical-minded engineers with a clear idea of the intended applications. With these projects in mind and an understanding of the key points we’ve covered above, hopefully, you will be in a good position to select the best hydraulic hand pump for your future projects.
