Olivite® Lined Process Pump

Olivite Pump

A Superior Pump For Handling Acids, Alkalies and Slurries.

Time Tested Design

FLSmidth, a well known and highly regarded manufacturer of equipment for the process industries, has been a leader in all-metal and polymer-lined centrifugal pumps for over 60 years. The lined Olivite pump, one of the most important in our line, has undergone literally hundreds of improvements in that time span. Today it is truly a state-of-the-art process pump for tough-to-handle materials.

The Impeller

The Olivite impeller is probably the most important reason why this pump has enjoyed such a wide-spread chemical and petrochemical industry acceptance through the years. The impeller is the most critical component in any process pump. It is where the work, and the wear happens. The Olivite impeller, despite its relatively light weight (compared to metal constructions), is very durable and highly wear resistant. It is made from Kynar® and reinforced with fine glass or carbon so that it will retain its shape during extreme temperature changes and prolonged service. Further, the impeller's low weight vastly reduces shaft deflection, which extends bearing life because wear and tear are reduced. In fact, dynamic balance of the molded impeller is practically perfect because of its uniformly smooth surface.
Other than weight, the Olivite pump impeller also offers a considerable advantage in its vane geometry. Vane geometry is important in generating capacity and head, and for a low net positive suction head requirement. The Olivite pump employs a semi-shrouded impeller shape, developed after a good deal of study and testing. This design promotes operating efficiency.

Liner Material

Kynar is a high performance fluorocarbon resin - a crystalline, high molecular weight, polymer or vinylidene fluoride. It combines a high degree of mechanical strength, impact and excellent abrasion resistance to most corrosive chemicals, including acids, alkalies and strong oxidizers. Kynar is serviceable in a broad temperature range of minus 80°F through 300°F.

Olivite OB-1 Installation Recommendations

Location of unit: Locate as to require shortest suction and discharge lines. Allow ample space for inspection and service.
Foundation: Size large enough to provide support and absorb vibration.
Alignment: Pump has to be level and sit firmly and uniformly at points of support.
Piping: To facilitate maintenance and prevent pipe strain to be transmitted into pump, install short flexible hoses in suction and discharge lines.
Seal Water: Assure ample supply of seal water. Seal water pressure to be 10 psi above 40% of discharge pressure.
NPSH: Calculate available NPSH and compare with curve. Available head had to exceed curve value.
Electrical Connection: To meet local code. Controls near pump.

The Olivite ANSI Pumps

Since 1930 FLSmidth has been the leader in the development and manufacture of lined centrifugal pumps. Alert to the ever-expanding needs of the chemical process industry, the company has developed a new line of corrosion and abrasion resistant ANSI centrifugal pumps. The Olivite pump possesses unique structural strength, a product of its rugged ductile iron construction. Without exception, the pumps meet, and in many instances exceed, the requirements of the ANSI This standard provides for dimensionally interchangeable pumps and for specific design features that minimize maintenance and replacement costs. The FLSmidth Super ANSI Pump follows a tradition of leadership in its superiority in the chemical process industry.

Highlights Of The Olivite ANSI Pumps

Lining & Lining Material The lining material is vulcanized and mechanically locked into the metal casing. A minimum thickness of 1/4" resists wear even under the most abrasive conditions. Available in Kynar® elastomer, which has superior corrosion and abrasion resistance. Parts are molded under high pressure to conform to close tolerance fits.
Casing The casing is cast ductile iron and affords the full strength normally associated with metal pumps. It is arranged for back pullout disassembly and has a top centerline discharge, meeting all ANSI requirements. Drain, gauge or vent connections can be provided at top and bottom of casing. Foot support affords maximum resistance to axial misalignment and distortion from pipe loads and eliminates the need for centreline supports.
Impeller Design The impeller is precision molded Kynar with a metallic insert to insure efficient power transmission. Vane design has been optimized to give high efficiency and very low NPSH. Solid Kynar vanes and shroud provide long life despite abrasion.
Impeller Adjustment This is the first truly external impeller adjustment. There are no jack screws, shims or feeler gauges required for adjustment, and no need to readjust mechanical seals. This makes the Olivite ANSI Pump the quickest and most economically maintained pump available.
Shaft & Shaft Sleeve The shaft is manufactured from high strength heat-treated chromium-molybdenum steel which exceeds ANSI deflection requirements. The hollow shaft provides an external adjustment of the impeller gap. A variety of shaft sleeve materials are available.
Frame The rugged cast iron frame provides maximum support and stability to the unit. It features a unique oil distribution system that assures bearing lubrication. The top rib is designed to provide a substantial and convenient lift point. The frame feet are slotted for easier back pullout.
Stuffing Box & Seals The Olivite ANSI Pumps offer more flexibility than other pumps. The oversized, completely lined stuffing box has room for a variety of mechanical seals. With the exclusive solid Kynar resilient sleeve, a corrosion resistant packed box becomes available for less critical applications.
Adapter The adapter is kept in a positive alignment with the frame by a precision pin. The adapter casing contains pipe tap connections for water circulation and cooling of packing or mechanical seals.
Complete Line FLSmidth makes sizes AA, AB, and A-50, A-60, A-70. The smaller sizes are available with either Kynar lining. Their maximum speed rating is 3550 rpm.

Olivite ANSI Installation Recommendations

Location: Pumps should be placed with short suction and discharge lines in order to hold pipe friction losses to a minimum. Ample space should be allowed on all sides of the pump so that it can be easily inspected while operating and quickly serviced when necessary.
Valves: Provide isolating valves near pump to allow maintenance on equipment.
Pressure Gauges: Install pressure gauges in discharge and seal water line in order to monitor pump performance. In chemical service, use diaphragm to safeguard gauge.
Piping Support: All piping should be independently supported. Pipe weight should not be carried by the pump. By installing short flexible hoses in the suction and discharge lines, piping vibration and noise is not transmitted and alignment assured.
Alignment: Accurate alignment should be maintained during operation. Misalignment will cause excess wear on coupling, packing and shaft sleeve and will result in bearing overheating. The pump must be level and sit firmly on all points of support.
Electrical Controls: All electrical connections should meet local codes. Locate the motor control station with "lockout disconnect" near the pump.
Foundation: The steel baseplate of the pump should be secured to a concrete foundation (over a solid support) with the foundation bolts embedded in the concrete. It is important to size the foundation adequately to absorb vibration and maintain alignment.
Seal Water: Assure ample supply of clean seal water. Seal water pressure should be 10 psi above 40% of discharge pressure.
Suction Piping: Keep the pump inlet free of air to maintain suction. Install piping without high points to prevent air pockets. Install piping with a slight gradual slope upwards toward pump. This will assure elimination.
NPSH: Calculate available NPSH and compare it with the curve. Available head has to exceed curve value.
