Borehole pump Speroni

To date, the situation on the market for centrifugal pumps for wells has changed markedly, if a couple of years ago Grundfos was especially popular, they were installed by almost everyone, but now they have lost their former popularity. For the whole of 2016, we installed only a couple of Grundfos. The price of these devices exceeded all reasonable limits and forced summer residents to pay attention to cheaper analogues. This contributed to the growth of the middle price segment, in which borehole pumps from Italy took their place. In one of our materials, we considered Italian Pedrollo pumps, and today it's time to look at slightly cheaper Speroni.
Recently, in the Russian market, the name Speroni has been removed and instead they write WATERSTRY. No need to worry, these are the same Speroni.

Having a wealth of experience in installing these devices, we will share our experience with you and give you our feedback on Speroni pumps. Also, let's talk about them. technical specifications how they differ from each other, and we will give the main pros and cons of these devices.

Speroni SQS Downhole Pumps

narrow series submersible pumps, 3" in size, designed for installation in wells drilled with 133 mm pipe + 117 mm or 110 mm plastic. Their diameter is 75 mm, which means that Speroni SQS can be lowered into narrower casing pipes. The minimum diameter of such a pipe can be calculated as follows: 75 mm diameter of the pump + 4 mm gap between the pump and the pipe + 15 mm thickness of plastic HDPE pipes. We get the minimum outer diameter of the pipe 94 mm.
The centrifugal borehole pump Speroni SQS is a real salvation for the summer resident. Previously, there were quite a few 3 inch pumps and almost always had to buy expensive Grundfos. Now you can install Speroni SQS and save several tens of thousands of rubles.

The Speroni SQS / WATERSTRY SQS model range consists of the following pumps:

• Speroni SQS 1
• Speroni SQS 2

Downhole pump Speroni SQS 1- devices with a nominal capacity of 1 m 3 / hour. The second value in the marking of the device indicates the pressure at which the declared productivity of 1 m 3 / hour is achieved.
With a smaller pressure, the productivity will increase, with a larger pressure, it will fall.
Only 4 models can be found on sale:

• Speroni SQS 1-45
• Speroni SQS 1-70
• Speroni SQS 1-90
• Speroni SQS 1-130

Characteristics of Speroni SQS 1

Prices for the popular submersible Speroni SQS 1-90 are very pleasant and start at 9500 rubles.

Centrifugal pump Speroni SQS 2— model with increased productivity of 2 m3/h at the head indicated in the model designation. As in any other well pump, with a lower head, the pump performance will be higher than 2 m 3 / hour.

SQS 2 Models:

• Speroni SQS 2-30
• Speroni SQS 2-45
• Speroni SQS 2-60
• Speroni SQS 2-90

Characteristics of Speroni SQS 2

The price of Speroni SQS 2-90 or WATERSTRY SQS 2-90, which are quite popular among summer residents, starts at 10,000 rubles.

The main pros and cons of Speroni SQS for wells

• The undoubted advantage is the price, it is simply savingly low and allows you to do without expensive 3-inch models.
• Reliability. Speroni's main series submersible pumps (STS and SPS) are quite reliable and have proven themselves, but they are made in Taiwan, while the SQS is made in China. Its release was launched not so long ago and there is no information about its real service life. But so far so good and no complaints.

• A narrow range of models does not allow you to choose a pump for a well with a capacity of 3 m 3 / h and above for water supply at home.

Value for money Speroni SQS is on high level.

Speroni STS pump

The Speroni STS downhole pump has a typical diameter of 4 inches or 98 mm, which limits the ability to install in some wells. For example, the minimum casing diameter into which this pump can be lowered is 125 mm or more.
The Speroni STS centrifugal pump itself has a stainless steel casing and noryl plastic impellers. But don't let that scare you, the pump is quite reliable and durable. Before handing over the well, the drillers have already pumped the well for you, you already have clean water, there is nothing in it that would erase this plastic.
The STS range is very wide and you can always find the best device for your well.
In Russia, the centrifugal Speroni STS is being replaced by the Waterstry STS. This is the same Speroni, but under a different brand.

Characteristics of SPERONI STS

Pros and cons of Speroni STS

• Excellent price, these models are quite cheap, often cheaper than other deep-well pumps from Italy.
• High reliability. The assembly of Speroni STS is established in Taiwan and, judging by the quality, they are assembled really well. We have great experience installation of these devices and complaints about their work have not yet been received.
  It can be assumed that the service life of Speroni pumps is more than 10 years, with periodic adjustment of the automatic pressure.
• A wide range of models, you can always choose a model for your well.

• No. Perhaps for someone it will be a minus diameter of 4 inches.

Good value for money.

Speroni SPS pump

These centrifugal pumps are made entirely of stainless steel. But the seals between the wheels are still rubber.
The question arises: which is better Speroni STS or SPS?
The model with the SPS index, by design, is a fairly simple pump; drillers often use it to pump a well. It is easily disassembled and assembled back, which cannot be said about Speroni STS. The summer resident, whose pump will always be in the well, all this is useless. Therefore, it makes no difference to you which pump to choose. The reliability of both are at the same high level, but the Speroni STS is a bit cheaper.

In Russia, you can also buy the Waterstry SPS model, it's just a renamed Speroni SPS.

Characteristics of SPERONI SPS

Pros and cons of the Speroni SPS borehole pump

• Good price.
• High service life. Over the years of our work with these pumps, no one has had problems. If you periodically adjust the automatic pressure (as it is required to do), then the resource of Speroni SPS can be more than 10 years.
• An even wider model range than the STS. You can choose a model for any domestic well. There are even very productive three-phase Speroni SPS on sale.

• More expensive than similar Speroni STS models.

The price-quality ratio is at a high level.

Pump design:
Downhole pump STS– submersible centrifugal multistage pump of normal suction. It consists of a pump part, which includes a certain number of stages - working chambers, which sequentially increase the pressure on the pump discharge pipe. Each working chamber contains an impeller, a diffuser and a chamber housing. The final stage of the pump is equipped with a non-return valve and an outlet with an internal thread. Fluid enters the hydraulic part through a hole in the adapter flange, protected from sand, drilling products and other foreign objects with a special strainer. The hydraulic part is designed according to the scheme with a floating impeller, which reduces the requirements for starting torque and reduces the abrasive effect of sand in water. In the STS series, the impeller is made of noryl, a very strong polymeric material, which is a mixture of polyphenylene oxide (PPO) and polystyrene (PS), which was developed by General Electric Plastics in 1966.
The connection between the electric motor and the pump is made in accordance with the NEMA standard.

Installation:
These pumps are designed specifically for downhole operation. As a result, the cooling of the electric motor here occurs with a stream of water moving from bottom to top along the motor to the inlet filter between it and the pump part. Therefore, it is allowed to install a downhole pump in a tank or well, but at the same time it is necessary to place the product inside the cooling casing, thereby simulating the working conditions in the well. It is also possible to mount the SQS pump horizontally with the outlet slightly above the intake.
The connection of a standard motor with a waterproof power cable must be carried out using the installation of a waterproof filler or heat-shrinkable adhesive sleeve
The cross section of the power cable is selected depending on the power of the electric motor and the required length to the power source. It is recommended to use a safety rope made of stainless steel, automatic pump shutdown (pressure switch, press control), a dry-running protection relay and a membrane tank.

Pump performance range
The main difference between the pumps of the STS series and the SPS is the material of the impellers and diffusers, as well as structural fabrication pump body. In the STS series, Noryl is used for manufacturing. A set of impellers and diffusers is placed in a sleeve that reliably protects the working elements of the pump. The surface of impellers and diffusers made of noryl has a low surface roughness, so the hydraulic parameters of the flow path are quite high.
To solve the problems of water supply of a private house, a pump with a capacity of not more than 5 cubic meters is enough, therefore, pumps of the STS series (with a pressure value of more than 30 atm.) Fully satisfy these requirements. This catalog contains all versions of the 4-inch STS pumps from the manufacturer. If it is necessary to have high pressure characteristics with a capacity of more than 10-12 cubic meters / hour, then it is necessary to choose SPS models.
