Horizontal pumps are often installed in sewage systems. Also, devices of this type are suitable for pumping water or oil. The main parameters should include power and pressure. The feed rate is measured in cubic meters per hour. In order to understand in more detail the features of the pumps, it is necessary to consider the existing types.
Classification
First of all, the 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. Console devices in which the drive is located in the upper part of the structure are highlighted in a separate subcategory. Liquid suction can occur through one or two openings. Depending on the type of outlet, devices with spiral and scapular channels are isolated.

Sprut JDW 42
This pump (horizontal one-piece) is manufactured with a steel diffuser. In this case, the manufacturer provides one pressure chamber. The diameter of the shaft is 34 mm. The inlet pipe is located at the rear of the housing. Impellers are horizontal. The body is made entirely of fine cast iron.
It is also important to note that one end of the shaft is fixed to a steel sleeve. The side bearings of the model are made of bronze. A protective cap is used to increase the permissible pressure. It is installed in a horizontal pump under the diffuser. In total, the model has three linings. The upper flange is fixed thanks to the bracket. The grease packing is applied to 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 circlip 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 impeller diameter is 402 mm. The maximum flow rate is 340 cubic meters. meters per hour. Pressure - no more than 50 meters. The drive in this case is installed low power. The maximum weight of the stand pump is 322 kg.
Saer NCB32 Pump Features
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 limit pressure indicator is at around 3.4 Pa.
The diffuser in the device is located above the shaft. The compensation 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 fluid of various densities.
Parameters of Saer NCB40
The indicated horizontal water pumps are multi-stage. 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 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 weight of the pump is 285 kg. The maximum flow rate reaches 310 cubic meters. meters per hour. Pressure indicator - no more than 46 meters.
Pump "Grundfos 5RT"
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 made entirely of fine cast iron. The bushings on the model are made of chrome steel. O-rings are standardly made of rubber. It is also important to note that the model has one packing under the shaft.
Description of the model "Grundfos 3RT"
Horizontal pumps "Grundfos 3RT" differ from other models with a large suction channel. The outlet pipe is located at the rear of the chassis. 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.
