Horizontal pump: types and specifications
Horizontal pumps are often installed insewer systems. Also devices of this type are suitable for pumping water or oil. The main parameters include power, as well as pressure. The flow rate is measured in cubic meters per hour. In order to understand the features of pumps in more detail, it is necessary to consider the existing types.
First of all, the pumps are distinguished by the number ofwheels inside the camera. There are single-stage, two-stage and multistage devices. It is also important to note that the shaft can be located in a horizontal or vertical position. A separate subcategory is dedicated to console devices, in which the drive is located at the top of the structure. Liquid suction can occur through one or two holes. Depending on the type of tap, devices with spiral and shovel channels are isolated.

The retaining ring in the device is made of steel. The feed parameter is not more than 230 cu. meters per hour. The electric motor is 12 kW. The head is equal to 45 meters.
Sprut JDW 42
This pump (horizontal monoblock)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. The body is made entirely of fine-grained cast iron.
It is also important to note that one end of the shaftfixed on a steel bushing. The side bearings of the model are made of bronze. To increase the allowable pressure, a protective cover is used. It is installed in a horizontal pump under the diffuser. In total, the model has three pads. The upper flange is fixed by the bracket. The sebaceous gasket is applied with a small thickness.
Sprut JDW 55
These pumps (fecal horizontal)are produced with two pressure chambers. It is also important to note that the device withstands a lot of pressure. The outlet connection is connected to the diffuser. In this case, the shaft is set to a small diameter. To increase the pressure, a circlip is used. It is made entirely of steel and is capable of withstanding heavy loads.
If we consider the parameters, then it is worth noting,that the diameter of the impeller is 402 mm. The feed rate is a maximum of 340 cu. meters per hour. Head - not more than 50 meters. The drive is installed in this case with low power. The maximum weight of the pump with a stand is 322 kg.
Characteristics of pumps Saer NCB32
This horizontal pump is manufactured withtwo impellers. The diameter of the outlet pipe is 34 mm. The pressure chamber is provided in an elongated shape. Due to this, the model has a very high pressure parameter. The indicator of the maximum pressure is at the level of 3.4 Pa.
The diffuser in the device is located above the shaft. Fastening of a compensation ring is carried out through a protective plate. The side bearings in the device are made of bronze. Also from the features it is important to mention a large gasket over the diffuser. Thus, the model is capable of pumping liquid of various densities.
Parameters Saer NCB40
These horizontal water pumps aremultistage. The drive in this case is used at 4.6 kW. All this allows you to withstand a lot of pressure. The pump body 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 feed parameter reaches a maximum of 310 cubic meters. meters per hour. The index of pressure is not more than 46 meters.
The pump "Grundfos 5RT"
Horizontal pumps "Grundfos 5RT" differvolumetric pressure chamber. In total, the device has two outlet nozzles. Their diameter is 46 mm. The impeller is fixed behind the shaft. The diffuser is completely made of fine-grained cast iron. The bushings of the model are made of chrome-plated steel. O-rings are usually made of rubber. It is also important to note that the model provides one padding under the shaft.
Description of the model "Grundfos 3RT"
Horizontal pumps "Grundfos 3RT" differfrom other models a large suction channel. The outlet is located at the rear of the housing. The diffuser is made of a small diameter. In total, the device has two impellers. The drive is connected to the pump by 4.3 kW. There is a sealing ring under the flange.
