Horizontal pumps are often installed in sewer systems. Also, devices of this type are suitable for pumping water or oil. The main parameters should include power, as well as pressure. The feed rate is measured in cubic meters per hour. In order to understand the features of pumps in more detail, it is necessary to consider existing types.
Classification
First of all, pumps are distinguished by the number of wheels inside the chamber. There are single-stage, two-stage and multi-stage devices. It is also important to note that the shaft can be located in a horizontal or vertical position. In a separate subcategory, console devices are allocated, in which the drive is located in the upper part of the structure. Liquid suction can occur through one or two holes. Depending on the type of outlet, devices with spiral and spatulate channels are distinguished.

Sprut JDW 42
This pump (horizontal monobloc) is manufactured with a steel diffuser. In this case, the manufacturer provides one pressure chamber. The shaft diameter is 34 mm. The inlet pipe is located at the rear of the housing. The impellers are in a horizontal position. Body made entirely of fine-grained cast iron.
It is also important to note that one end of the shaft is fixed on a steel sleeve. The side bearings of the model are made of bronze. A protective cover is used to increase the allowable pressure. It is installed in a horizontal pump under the diffuser. In total, the model has three linings. The top flange is fixed thanks to the bracket. The greasy packing is used in a small thickness.
Sprut JDW 55
These pumps (horizontal fecal) are produced with two pressure chambers. It is also important to note that the device can withstand a lot of pressure. The outlet pipe is connected to the diffuser. In this case, the shaft is installed with a small diameter. To increase the pressure, a retaining ring is used. It is made entirely of steel and is able to withstand heavy loads.
If we consider the parameters, it is worth noting that the diameter of the impeller is 402 mm. The maximum feed rate is 340 cu. meters per hour. Pressure - no more than 50 meters. The drive in this case is set to low power. The maximum weight of the pump with the stand is 322 kg.
Saer NCB32 pump specifications
The specified horizontal pump is manufactured with two impellers. The diameter of the outlet pipe is 34 mm. The pressure chamber is provided with an elongated shape. Due to this, the model has a very high pressure parameter. The limiting pressure indicator is at around 3.4 Pa.
The diffuser in the device is located above the shaft. The wear ring is fastened through the protective plate. The side bearings in the device are made of bronze. Also of the features, it is important to mention the large gasket above the diffuser. Thus, the model is able to pump liquiddifferent densities.
Saer NCB40 parameters
The indicated horizontal water pumps are multistage. The drive in this case is used at 4.6 kW. All this allows you to withstand a lot of pressure. The pump housing is made of fine-grained cast iron. However, all bushings are made of stainless steel. The shaft of the model is installed with a diameter of 57 mm. The bracket is used with a protective plate. The maximum mass of the pump is 285 kg. The supply parameter reaches a maximum of 310 cu. meters per hour. Pressure indicator - no more than 46 meters.
Pump "Grundfos 5PT"
Horizontal pumps "Grundfos 5PT" are distinguished by a volumetric pressure chamber. In total, the device has two outlet pipes. Their diameter is 46 mm. The impeller is fixed behind the shaft. The diffuser is entirely made of fine-grained cast iron. The bushings of the model are made of chrome-plated steel. O-rings are made of rubber as standard. It is also important to note that the model has one packing under the shaft.
Description of the Grundfos 3RT model
Horizontal pumps "Grundfos 3PT" differ from other models in a large suction channel. The outlet is located at the rear of the housing. The diffuser is made of small diameter. In total, the device has two impellers. The drive is connected to a 4.3 kW pump. There is an o-ring under the flange.
