Portable Peristaltic Pump,Hand Held Peristaltic Pump,Battery Powered Peristaltic Pump,Sampler Peristaltic Pump Baoding Chuangrui Precision Pump Co., Ltd. , https://www.crprecisionpumps.com
It has the advantages of a peristaltic pump, and a single tube is used alone
without cross-contamination; a wide flow range, reversible forward and reverse operation.Replaceable
charging power, light and portable, flexible operation, can easily cope with stratified sampling, deep water
sampling, sampling of gas samples, high-viscosity liquids, suspended liquid containing tiny particles, etc. It is
especially suitable for field operations.
DFG (DFRG) series of single-stage vertical pipeline centrifugal pump
First, the product description DFG (DFRG) series single-stage single-suction vertical pipeline centrifugal pump for the direct-connected pipeline pump structure, the impeller mounted on the motor shaft, with a smooth running simple structure, easy maintenance and repair, easy installation and covers an area Province (with the ordinary horizontal pump than the area of ​​more than 30%) and other characteristics; products meet GB / T5657-1994 "Centrifugal Pump Technical Specifications (III)" standard; can transport medium temperature does not exceed 105 ℃ water or physical Chemical properties similar to other liquids in clear water. Second, the product features 1, energy-efficient: CFD CFD, analyze and calculate the pump pressure distribution and speed distribution, optimize the pump flow channel design, to ensure that the pump has an efficient hydraulic shape line to improve the pump efficiency. 2, easy installation and maintenance: vertical pipe structure, the import and export of the pump can be installed in the pipeline as any position and any direction, installation and maintenance is very convenient. 3, smooth operation, safe and reliable: Motor shaft and pump shaft for the coaxial straight, high concentricity, stable operation, safe and reliable. 4, stainless steel sleeve: shaft sealing position is relatively easy to rust, direct-coupled pump shaft once corroded, easy to cause mechanical seal failure. DFG (DFRG) pumps are fitted with stainless steel bushings to prevent rusting, improve shaft life and reduce operating and maintenance costs. 5, Bearing: pump equipped with motor, Y (Y2) 280 below the shaft end bearings (including Y180 the following blade end bearings) with closed bearings, normal use, maintenance-free motor bearings. 6, mechanical seal: mechanical seal base member is generally used rubber bellows structure, the traditional mechanical seal shaft seal by the O-ring seal into two parts of the rubber seal, sealing water in the media to improve the sealing effect. Third, the working conditions of flow: 2 ~ 1400m3 / h Head: 5 ~ 130m System maximum working pressure: ≤ 1.6MPa Operating temperature: Normal DFG -15 ℃ ~ +80 ℃ hot water type DFRG +80 ℃ ~ 105 ℃ Matching motor: Insulation class: Class B or Class F Protection class: IP44 or IP54 Ambient temperature: ≤ + 40 ℃ Motor type: Y or Y2
