Rating of the best crimpers for 2022

Hydraulic test pumps are indispensable equipment during construction and repair, ensuring that there are no leaks in water supply, heating, fire protection systems. They ensure that pipelines will work successfully under pressure.

In our review, we will provide recommendations: what to look for in order not to make a mistake when choosing a product, which company model is better to buy. We will get acquainted with popular manufacturers, a description of their brands, we will orient you at an average price.

Types of "crimpers", how to choose them correctly

A qualified person uses the functionality of a hydrostatic unit to pump liquid at high pressure into a water supply system. The test provides confidence that the components have been assembled correctly, after which you can install bathroom fixtures or other equipment.

Testing takes place at the lowest point in the system. Inspectors visually inspect pipes, connections and fittings for leaks, monitor pressure gauges. The readings must not deviate from the allowable test pressure readings. Sometimes significant drops indicate a faulty pressure gauge or equipment, but can also potentially reveal a major problem with system integrity.

Pressure testers are used to test a variety of water systems in residential and commercial buildings, from sprinklers to plumbing lines. The basic features are the same across all test units, but power, durability, portability, and handling can vary greatly by variety.

• Most standard plumbing pressure test pumps are electric. They produce less power than gas appliances, but they have enough energy for most systems. Many experts note the convenience of connecting electrical equipment, no need to mess with fuel, this explains the popularity of this model. Electric units do not generate steam during use, which is essential indoors. You can buy models that run on car batteries. This allows them to be used in unfinished buildings without operating voltage.
• Powerful gas appliances quickly pressurize the system, filling it with water.They are typically used for large diameter pipe work, testing risers in tall buildings.
• Manually operated equipment pumps no more than 8 liters of fluid per minute into the system. It is less common among experts. Many contractors avoid the inconvenience associated with the need to pump water on their own, with their own hands, to wait longer.
• Crimpers for cables.

The natural pressure in the system influences the choice of apparatus for testing. There are other important criteria that inspectors should consider:

• It is important to note the diameter, length of the tested pipe. A small residential system is tested quickly, it is not difficult to reach the test pressure, so manual units can be used.
• The type of system is another important factor influencing the choice of equipment. Filling a dry riser will take longer than a wet one.
• The size and height of the building is also an important selection criterion, due to gravity.

Weight plays an important role during equipment acquisition. It affects the speed of movement of the contractor on construction sites. As a rule, the more powerful the machine, the more it weighs. Large units may require two people to move and are often mounted on wheels. The lightest machines use aluminum components, which are significantly lighter than parts made from other materials.

The best machines made of "flying" metal are more resistant to damage from corrosion, freezing. It is known that the casings of old models made of cast iron and other metals crack during vibration at low temperatures. Brass components can also help reduce weight and improve equipment rust resistance.

You have a choice between cheap low pressure brass troughs, to 316 stainless steel pumps from well-known brands. They will all do their job. Where to start in order to choose the best machine that suits your needs and budget, here are some tips:

• It is necessary to understand what kind of liquid and pressure in the system. This is a very important question. The pipe can be filled with mineral oil, fuel, water, brine, synthetic hydraulic fluids, and a variety of other chemicals. The pressure can vary from fractions of a bar up to 1000 bar.
• Budget, "industrial" manual hydraulic machines are versatile, meet high requirements, they can easily handle oil pumping. As for the fuel, which has a lower viscosity, other equipment designs are possible. We would advise looking at a more specialized unit with poppet check valves, they eliminate leakage. No need to use metal ball valves for low viscosity liquids.
• Inexpensive machines with a chute are used for water, which can be a problem. It is corrosive, so you need to look for an apparatus that can withstand pressure and not corrode.
• Whatever your budget, it is important that the device performs accurately from day one. Typically, pressure pumps run into trouble when they are left filled with water for long periods of time before being reused.
• The construction of stainless steel, bronze solves the problem of corrosion, but its price is quite high. Compounds successfully resist rust, their disadvantage is the low strength of the unit.

Be aware of hidden device maintenance costs.Some users will buy cheap machines to do one test. Always strive to minimize corrosion, use quality parts during repairs.
