EF CENTRIFUGAL PUMPS

EF CENTRIFUGAL PUMPS

· Non-metallic solution contact High temperature polypropylene, PVDF or ECTFE (Refer to a chemical resistance chart)

· Flow rates: 175 U.S. GPM or 130 ft. TDH @ 60Hz Metric: 552 LPM or 28 M @ 50 Hz

· 304 Stainless “long” sleeve impeller insert

· Single seal mechanical, or Double seal mechanical made of silicon carbide seal faces with EPDM or Viton® soft seal components

· Centrifugal Pump Design – quiet, vibration-free

· NPT connections molded into casing · Chemical duty motor WEG motors come standard (1.0 – 7.5 HP) 1.15 service factor at 50 or 60 Hz.

· Cast bell housing coated in epoxy allows for multiple angle indexing of outlet or 60 Hz.

Finally a pump that is not only made from durable polymers,but extremely cost effective. Completely Chemical resistant, both inside and out with process fluids in contact with polymers not metal. Top of the line seals as standard offerings.

We use the best engineered plastics such as KYNAR come as standard offerings, and provide constant reliability and durability in the worst chemical applications and processes. The Impeller is molded with tight tolerance, onto and long stainless shaft made of 304 stainless. The stainless insert is in full contact with JM type motor shafts for the full length of the impeller sleeve.

This means metal on metal contact between motor and impeller for superior wear resistance and long life. The pump can be used for solutions containing abrasives using a double mechanical seal which ideal for abrasive solutions or those containing high salt concentrations like “E”nickel ot other electroless plating solutions. Either Viton or EPDM elastomers are available on the ‘EF’ pump.

At Elmira Pump Company Carry many different Standard Models

Standard models are constructed of polypropylene, PVDF, or ECTFE with threaded connections. The motor shaft is protected by the impeller sleeve assembly. Elastomers are EPDM or Viton. Impellers are enclosed. The mechanical seal is type 21, externally mounted with stainless steel components not in solution contact. A double mechanical seal is recommended for solutions containing abrasives and for high temperature or other critical service. Close coupled motors are NEMA ‘JM’ or metric (IEC) standard. The motors designated NEMA can operate on 50 or 60 Hz at full rated horsepower. Consult Application Engineering Department for BSP fittings or adapters.

How to pick the right model: Select flow curve number providing the desired performance Form the Flow Curve Tab.

-Then match to Model Number listed in the Pump Tables. Standard models include silicon carbide single mechanical seal with EPDM or Viton elastomers.  Motor HP is non-overloading at full capacity with 1.1 specific gravity fluids.

Filterpress

Filter Press

A filter press is commonly used in three applications: as a fixed volume, batch pressure filter; as a polishing filter to remove solids from a stream; and as a variable volume filter through a filter plate.

Filter press is a separation process, specially employed by solid/liquid separation using the principle of pressure drive, provided by a slurry pump. Filter press is a fixed volume and batch operation, which simply means that the operation must be stopped to discharge the filter cake before the next batch can be started. The major components of filter press are skeleton and filter pack. The skeleton holds the filter pack together while pressure is being developed inside filter chamber. It however can only hold a specific volume of solids.

In operation, slurry is pumped under pressure into the press chambers through the manifold at the stationary head of the filter press. As each chamber fills with slurry, the liquid passes through the cloth medium, across the drain-field, through the drain ports and exits via gravity out of the corner discharge eyes.

The prime function of the filter media is to provide a porous support structure for the filter cake as it develops and builds. Initially, some solids may pass through the cloth media causing a slight turbidity in the filtrate, but gradually the larger particles within the slurry begin to bridge the openings in the media reducing the effective opening size. This allows smaller particles to bridge these reduced openings initiating the cake filtration process. Once a layer of solid particles achieves 1 to 2 mm in thickness, this “precoat” layer serves to separate out finer and finer particles as the cake builds in thickness, yielding a filtrate that is very low in turbidity.

Maintaining a clean environment, production of food and beverages, and development of essential medicines require filters that separate solids from liquids. ANDRITZ offers filter presses for a wide variety of applications and industries, ranging from treatment of wastewater sludge and drinking water, the food and beverage industry, the chemical industry, pharmacy and mining, to paper production. Applications include:

  • chemicals and pigments
  • metallurgical products and ores
  • minerals and inorganic products/mining
  • industrial and municipal wastewater treatment
  • food and pharmaceuticals
