Benefits of Japanese pumps Tsurumi

A – Absolute waterproof
Capacity to enter into the pump wires and the wires themselves are often vulnerable to capillary moisture from the low negative pressure created inside the pump. This can cause damage to the pump. Inputs of electrical wires and each wire individually to the pumps and aerators Tsurumi protected by special epoxy linings completely exclude even the capillary penetration of oisture.

B – Business continuity in the “dry” conditions!
Due to the bi-metallic sensor located above the motor and the pump power is interrupted if the voltage rises or begins to Read the rest of this entry »


3G. Centrifugal pump before start-up must be completed by the pumped liquid

Fragment № 3G CENTRIFUGAL PUMP

A centrifugal pump is part of the dynamic hydraulic vane pumps (see Figure 2 fragment number 1G). In the centrifugal pump energy is imparted by the fluid dynamic effects on her shoulder blades rotating impeller.

The scheme of single-stage horizontal centrifugal pump with axial inlet and outlet spiral shown in Fig. 1. In the body of a pump shaft 2 located impeller vanes 3 with 4. Shoulders are usually fastened between two discs 5 and 6. On the suction side is connected to the housing suction tube 7, which connects to the inlet pipe. Discharge side housing has a spiral tap 8 (in some drainage pumps can be circular), ending pressure port 9, which connects the discharge pipe.


Fig. 1

Centrifugal pump before start-up must be completed by the pumped liquid. After starting the pump blades rotating impeller has a direct force on the particles of the fluid that fills the interscapulum. Under the action of centrifugal forces the liquid moves from the center to the periphery of the Read the rest of this entry »


The pumping system consists of two horizontal Single-stage units of type NB (working and reserve), suction and discharge manifolds


GRUNDFOS developed Russia’s first fire-fighting capacity of up to 300 m3 / h

The company has improved GRUNDFOS complete installation for fire extinguishing systems HYDRO MX. Expansion of range; installations by creating stations based on the Single-stage pumps NB increased the plant capacity factor of 6. According to specialists, the new analogues HYDRO MX in Russia to date, no.

HYDRO MX can be used in sprinkler systems and deluge of water and foam fire fighting, as well as in systems with hydrants. The pumping system consists of two horizontal Single-stage units of type NB (working and reserve), suction and discharge manifolds, control box, stop and control valves, control devices and automation. When assembling HYDRO MX uses components and parts, certified Federal Institute of Fire Prevention Emergency Situations Ministry.

“This product is fully focused on the Russian market, – says Roman Marihbeyn novelty, head of the Read the rest of this entry »


The use of this series can save up to 40% of operating costs.

Indicators Wilo Stratos GIGA exceeded all future requirements of new European regulations and directives on energy efficiency of electric motors.

Concern Wilo Se introduced a new high-efficiency pump Wilo-Stratos GIGA. Wilo-Stratos GIGA – is a completely new design group Wilo SE, the first pump motor is equipped with glanded EC with extremely low power consumption. This innovative product line perfectly complemented the energy pump “Wilo-Stratos”.

A new series of Stratos GIGA – designed for use in high-performance heating and cooling systems.

At the heart of the development of the pump “Wilo-Stratos GIGA” – is energy-efficient synchronous motor with a rotor of permanent magnets and technology, “Electronic Control”. Energy efficiency pump has a high motor efficiency, which, in conjunction with the new hydraulic system is 94% in engine power 4.5 kW. The energy efficiency of the pump exceeded all future requirements of new European regulations and Read the rest of this entry »


The materials presented in the form of short articles (fragments) in the most simple statement (for the understanding of articles rather the knowledge gained in high school)


Theoretical Hydrodynamics of the company Elite. Fragments № 0-1. Symbols and an overview of the pumps.

Dear readers. Now we begin the publication of theoretical material on hydrodynamics, namely, those materials which, one way or another, relate to pumps. The materials presented in the form of short articles (fragments) in the most simple statement (for the understanding of articles rather the knowledge gained in high school). Every article has its own code in the serial number and letter designation section. For example, the code of Article 1G means that it is the first story in “Hydrodynamics.” The article, number 0 – the total for all sections (in which the symbols found in the stated material).

We hope that this series will help you more conscious approach to the choice and maintenance of pumping equipment that will allow you to make better use of your resources and resources of your company.

Our plans are also a series of articles on the Read the rest of this entry »


SP pumps in the performance of N (SST. 1.4401), and the performance of R (stainless. Steel 1.4539), which are supplied with engines MS6
