The Kinney Liquid Ring Pump from Tuthill Vacuum Systems is a non-pulsating vacuum pump thatremoves gases through the use of rotating impeller blades that enter and leave a ring of liquid. Theimpeller forces this sealing liquid to the periphery of the pump casing, where it forms a moving ringof liquid around a center void.

The impeller shaft is mounted above the center line of the casing. Thus, the blades, although rotatingconcentrically, are located eccentrically with respect to the casing and the ring of liquid. The pumpsaxial suction and discharge ports are exposed to the void but separated by the impeller blades andthe ring of liquid. As the process gas or vapor is drawn into the pump through the suction port, it istrapped between the impeller blades and the liquid ring. The rotating blades enter deeper into theliquid ring, progressively reducing the entrapment space, compressing and then exhausting the gasthrough the discharge port. The liquid ring acts like a liquid piston. So the entire pumping operationis accomplished without vanes, valves, pistons or any metal-to-metal contact.

Design Features

Impellers positively locked to shafts

Reliable mechanical seals for high-integrity sealing and low shaft friction

Center-anchored tie rods allow access to either end of the pump without total disassembly

Precision casting and CNC machining eliminate the need for body gasketing (process dependent)

Optional Equipment

Inlet check valve- Automatically isolates the pump from the

inletsystem when the vacuum pump is shut

down- Prevents the back flow of sealant and air

Vacuum relief valve- Opens at a preset pressure and admits

ambient air to the pump inlet to prevent pump

cavitation

Inlet isolation valve- Isolates the pump from the process

chamber

Inlet vacuum gauge- Used to observe the inlet vacuum level

at the pump

SYSTEMS OVERVIEW

An important consideration in planning a liquid ring vacuum pump installation is the design of the

sealant system and its effect on the performance of the pump. TVS recommends early consideration be

given to sealant system design because there are several elements of pump sizing, selection and system

design that will be affected by the choice of the sealant system.

Operating pressure is affected by sealant temperature, flow rate, specific heat,

density and viscosity.

The gas load may influence the selection of the sealant and the sealant system.

The economic priorities may indicate a system where process recovery can be

accomplished or where water conservation can be achieved.

The operating costs, in terms of horsepower and water costs will almost always

have an influence on design decisions.

Although there are variations, there are three basic types of sealant systems from which to choose:

No-sealant Systems

Partial-sealant Systems

Full-sealant Systems

The No-sealant Recovery System takes water directly from the water main, circu-

lates the water and discharges it to drain without recirculation. This arrangement

is most common on smaller pumps or in installations where water conservation

or contamination is not a factor.

KINNEY

SYSTEMS OVERVIEW6

KINNEY

SYSTEMS OVERVIEW

The Partial-sealant Recovery System

discharges water and gas into a

gas/water separator tank where the

mixture is separated. The gas is vented

to the atmosphere, a portion of the seal

water is disposed of through an over-

flow; the remainder of the seal water is

retained in the separator tank for recir-

culation. Makeup water is added to

maintain proper sealing water temperature, which is essential to maintaining the operating pressure.

In order to reduce the amount of makeup water required, the system may be fitted with a temperature

modulation valve.

The Full-sealant Recovery System is a closed loop system. The sealant is recirculated through a heat

exchanger and cooled by a separate cooling water source. Since there is no contact between the

sealant and the cooling water, there is no cross contamination.

ENGINEERED SYSTEMS OVERVIEW

Multiple-stage liquid ring vacuum systems consist of liquid ring vacuum pumps in combination

with lobe-type mechanical boosters and/or air ejectors. These systems deliver higher pumping

speeds at deeper vacuum, and are particularly well suited for applications in the process industries,

especially those in the 10 to 125 Torr operating range. Within this range, multiple-stage liquid ring

vacuum pump systems are inherently more stable and have a flatter performance curve than single

stage systems.

In multiple-stage vacuum systems each stage compresses the process stream at the inlet to the next

stage, increasing the systems range well beyond that of single-stage systems. Pumping capacity is

increased while vacuum levels are reduced significantly. Sealant systems may be once-through, par-

tial recovery or full recovery. Full recovery systems may be furnished with heat exchangers for air

or water cooling.

Mechanical BoosterLiquid Ring Pump

MechanicalBooster/BoosterLiquid Ring Pump

Mechanical Booster/Air EjectorLiquid Ring Pump

The mechanical booster, a lobe-type pump, handles large volumes of

gas over relatively small differential pressures. Thus, smaller liquid

ring pumps may be employed efficiently on high-gas volumes. Two

figure eight-shaped rotors, statically and dynamically balanced,

counter-rotate and compress the process stream by trapping it between

the rotors and the pump housing. When the vacuum created by the

liquid ring pump reaches a predetermined level, the booster automatically

cuts in. Cut-in pressures may be adjusted for maximum energy savings.

Adding a second mechanical booster extends system operation to

vacuum levels as low as 2.0 mmHg Abs. Like single-booster sys-

tems, the boosters are not energized until vacuum reaches a pre-

set level. Smaller boosters with larger motors are used for booster

operation over the full pressure range. By adjusting the cut-in

pressures for both booster stages, the system can be tuned for

maximum efficiency and energy savings with a wide range of

Booster

In this system, an air ejector is inserted between the mechanical

lobe-type booster and the liquid ring pump. This enhances pump

performance across a wide range of sealant properties, and lowers

the booster discharge pressure. The result is significantly lower

continuous operating vacuum levels without increasing horsepower

requirements. Ambient air or recirculated process gas is used as

motive gas in the air ejector. To allow high-capacity pumping at 30

Torr or above, motive air shut-off valves and a bypass manifold may

be added to the system. Air ejectors are also used without boosters

for certain applications where system simplicity is beneficial.

Tuthill Vacuum Systems (TVS) is a pioneer in the development

of vacuum pump technology. Introduced in 1926, the Kinney

rotary piston vacuum principle still sets the industry standard

for high performance, reliability, low maintenance and quiet

operation in a mechanical vacuum pump design. These same

performance features are demonstrated in all the TVS vacuum

pump product lines: liquid ring pumps, dry pumps, vane

pumps and our main line of rotary piston pumps. In addition,

all pump designs can be incorporated in complete TVS-

engineered vacuum systems.
