Product Description:

FEATURES:

Vertical Multistage grundfos water Pump is the latest model with the features of energy-saving and less space demand, easy to install and has stable performances.

 

1. With its 304 stainless steel shell and wear-resistant axle seal, there is no leakage and it can live long service life.

 

2. With hydraulic equilibrium to balance the axial force, the pump can run more smoothly, less noise, which can be easily installed in same level pipelines, enjoying better installation conditions than DL model.

 

3. With these features, GDL Pump can easily meet the needs and requirements for water supply and drain foe high building, deep well and firefighting equipments.

Q:What is a positive displacement pump? He Weizheng displacement?
The principle and structure of displacement pumps are similar to those of hydraulic motors. Positive displacement is the pump outward to provide flow and pressure, that is, conventional pumps. A negative displacement pump is a hydraulic motor that rotates by external pressure and flow
Q:What is the pump lift voltage? And how to suppress the pumping voltage rise?
The reverse voltage and torque electric torque instead, and the motor has strong braking torque, forcing the rotor quickly stopped, but usually AC-DC-AC converter is the main power AC/DC rectifier circuit is irreversible, and therefore can not return to the power grid, resulting in the main circuit of the capacitor voltage increases two that is called the pump voltage.
Q:What is an industrial water pump?
Classification by usagePump, circulating pump, fire pump, pressure test pump, sewage pump, metering pump, sanitary pump, dosing pump, pump, pump, gelatinization defoaming pump, flow pump, oil pump, water pump, drainage pump, drainage pump, dredging pump, sprinkler pump, booster pump, high pressure pump, heat pump high temperature, low temperature, pump pump, condensate pump, heat pump, cooling pump, heating pump, deep well pump, analgesic pump, pump, pump, chemotherapy, blood pump material pumping pump, pump, pump, sulfur removal, shearing grinding pump fuel pump, pump, pump, quillback bath source heat pump, filter pump oxygen pump, pump, shampoo, injection pump, air pump, gas pump, pump, pump, art odorization pump chopped
Q:What is a feed pump?
In general, high lift pumps are required with a front pump (which is similar to the feed pump of the landlord) or a low position;
Q:What is the series of pumps? What's the difference between a unipolar and a multistage?
You're talking about a centrifugal pump. His series says the number of slices of the impeller (excluding the wheel, that is, the wheel)
Q:What are the general water pump failure, how to repair?
Troubleshooting of water pumpFirst, the water pump does not cause water analysisThere is air in the inlet pipe and pump body(1) before the water pump is started, the water is not filled enough. Sometimes it seems that the water has been discharged from the vent hole, but the pump shaft is not rotated. The air is completely discharged, resulting in a small amount of air remaining in the inlet pipe or pump body.
Q:What is the main difference between SK water ring vacuum pump and 2BV water ring vacuum pump?
The unified corrosion resistant design of bronze impeller improves the corrosion resistance of the pump, and the stainless steel material is more suitable for more severe applications;
Q:What are the starting and stopping procedures for centrifugal pumps?
The use of centrifugal pump can be divided into three steps, namely, start, run, stop.Start: you should do the following preparation before starting:(1) check the water pump equipment in good condition.(2) the bearings are filled with oil, the oil level is normal, and the oil quality is qualified(3) all the inlet valves of the centrifugal pump are opened.(4) pump water injection or vacuum pump diversion (except for flow), open the vent valve exhaust.(5) check the leakage of shaft seal. It is advisable to fill the seal with a little drop of water.(6) the motor rotates in the right direction.
Q:What is the lift of diaphragm pump?
Hello, pneumatic diaphragm pump head is liquid, the energy obtained through the pump is called the head, it is related to the flow rate and pump speed, liquid density.Please adopt.
Q:How high can the pneumatic diaphragm pump be?
Diaphragm capacity, high temperature, pneumatic diaphragm pump ability, high temperatureMany users do not know how high the temperature resistant diaphragm pump, diaphragm pump either electric diaphragm pump or pneumatic diaphragm pump products it cannot do without diaphragm attachments, diaphragm materials mainly fluorine rubber, rubber, rubber, polyether road three EPDM, PTFE several, if not considering the gas temperature resistant diaphragm made of stainless steel. The temperature to 600 degrees of diaphragm pump diaphragm pump, but must use the diaphragm, so the diaphragm pump can Naiduo high temperature depends entirely on the diaphragm was affected by temperature, following to share various diaphragm pump diaphragm material and different material temperature choice diaphragm pump product right:
