Product Description

CRNE-HS and CRN-SF Vertical Stainless Steel Multistage Centrifugal Pumps

 

The CRNE-HS single pump and CRN-SF double pump are a type of vertical stainless steel multistage centrifugal pump system. Made of stainless steel material of AISI 316 grade, they are capable of withstanding high-pressure limit conditions. They are highly suitable for fields such as cleaning systems, water treatment systems, industrial equipment, boiler feed water systems, filtration, and reverse osmosis.

 

In high-pressure applications, pumps usually face various extreme conditions, such as high inlet pressure, high operating pressure, frequent start-up/shut-down, and pressure pulsation. These conditions may cause the pump to be overloaded, thereby increasing the wear and tear of pump components (such as motor bearings and shaft seals) and shortening the service life of the stainless steel centrifugal pump. If the flow rate is lower than 5 m3/h, please use the CRNE-HS single pump model; if the flow rate exceeds this value, please use the CRN-SF double pump model.
 

Solution for Sensitive Shaft Seal Pressure Stress   Eliminates pressure stress on sensitive shaft seals, providing a maximum pressure of 50 bar at up to 120°C. Compact Design   Reliable, efficient, and space - saving design. High Efficiency   CRNE 1 - HS and CRNE 3 - HS stainless steel centrifugal pumps are equipped with high - efficiency IE5 MGE motors with integrated variable - frequency drives. Suitable for Corrosive Liquids   Suitable for mildly corrosive liquids.

It is a vertical multistage centrifugal pump with the suction and discharge ports at the same level. The pump head and base are made of cast iron, while all other parts in contact with the liquid are made of stainless steel (EN 1.4301).
 

CRNE 3 - 23 Q - P - T - E - HQQE
A non - self - priming high - pressure multistage vertical centrifugal pump with suction and discharge ports at the same level can be easily installed in a horizontal single - pipe system. The stuffing box is inverted to ensure that the shaft seal is not affected by the higher pump discharge pressure. The material of the pump body in contact with the liquid is high - grade stainless steel. A multistage vertical centrifugal pump with suction and discharge ports at the same level can be easily installed in a horizontal single - pipe system. Electrical energy is transmitted through a split - type coupling. The pipe connection is achieved through a PJE (Victaulic®) coupling. An asynchronous motor with three phases, a cooling fan and feet is installed on the water pump. The motor terminal box contains a frequency converter and a PI controller. This enables the system to continuously adjust the motor speed, allowing the water pump to be optimized for operating conditions.
