CONVENTIONS, SAFETY AND DATA PLATE

Operator’s Manual 1808 022016 ENG 3

Conventions, Safety and Data Plate

SAFETY PRECAUTIONS FOR

ROTARY PISTON PUMPS

Please read the following safety information before

operating the vacuum pump.

• Do not operate the pump without the beltguard

properly attached.

• Disconnect the pump from the electrical supply

at the main disconnect before removing the

beltguard. Replace the beltguard before

reconnecting the power supply. Operating the

pump without the beltguard secured in place

exposes people in the vicinity of the pump to risk

from rotating drive parts.

• Do not operate the pump with oxygen-enriched

gas in the suction line, where the proportion

of oxygen exceeds 21%, unless the pump has

been prepared with an inert ﬂuid suitable for the

application. Pumping oxygen-enriched gases

with mineral oil or other non-inert ﬂuids can

cause an explosion in the pump, resulting in

damage or injury.

• Take precautions to avoid prolonged or

excessive exposure to oil mist or process

materials from the discharge of the pump. Do

not allow the pump to discharge into a closed

room or a room without adequate ventilation.

Always use a discharge oil mist eliminator

unless the pump discharge is vented to the open

air. Venting the outlet of the oil mist eliminator to

the open air is highly recommended.

• Do not restrict the pump discharge line in any

way or place any valves in the discharge line.

The vacuum pump is a compressor and will

generate high pressures without the motor

stalling when operated at low suction pressures.

Excessive pressure buildup could cause

damage or injury.

• Disconnect the pump from the electrical supply

at the main disconnect before dismantling

or servicing the pump. Make sure the pump

is completely reassembled, the beltguard is

replaced, and all drain and ﬁll valve and plugs

are closed before reconnecting the power

supply.

• Accidental starting or operation of the pump

while maintenance is in progress may cause

injury or damage.

• Lift only with the lifting eyebolts supplied with

the pump. Do not lift equipment attached to the

pump with the eyebolts supplied.

• Do not touch hot surfaces on the pump. In

normal operation at low pressures, surface

temperatures will not normally exceed 180°F

(82°C). Prolonged operation at 200 Torr may

cause surface temperatures up to 220°F

(104°C).

• GEAR DRIVES UNITS: During operation,

gear drive units may become sufﬁciently hot to

cause skin burns. Take care to avoid accidental

contact. After extended running, the lubricant in

gear units and lubrication systems may reach

temperature sufﬁcient to cause burns. Allow

equipment to cool before servicing or performing

adjustments.

Conventions, Safety and Data Plate

DATA PLATE

MODEL NUMBER: The speciﬁc model of the blower

SERIAL NUMBER: Unique to each blower

YEAR: Year of manufacture

This manual describes instructions and precautions

to be observed in the handling and maintenance

of Tuthill Vacuum & Blower Systems Kinney

KD Rotary Piston Vacuum Pumps. It is strongly

recommended that those who operate or maintain

the pump read this manual carefully prior to pump

operation, to ensure personal safety and pump life.

WARNING

Keep body & clothing away

from machine.

During operation, keep body

and clothing away from inlet

and outlet of the pump.

WARNING

Do not operate without guard in

place. Assure that the guards

are in place and secure prior to

operation.

CAUTION

Hearing protection is required

while the pump is in operation.

At ultimate pressure noise

levels are 75 dBA, however

due to process or installation

conditions noise levels may be

higher.

CAUTION

Do not touch hot surfaces.

Do not touch the vacuum pump

while it is in operation and

assure that the pump is cool

before touching, when not in

operation.

Operator’s Manual 1808 022016 ENG 5

LIFTING

WARNING

The vacuum pump must be handled using

an appropriate device such as a fork truck

or appropriate lifting device. See Table 4-2

on page 7 for approximate weights. Care

should be taken to assure pump does not

overturn during handling and installation.

Operator’s Manual 1808 022016 ENG

GENERAL

The vi sual difference between the two pumps is

in the oil separators. Internally, the pistons, cams,

and slide pins of the K D-5 0 are treated to be able

to tolerate the increased speed. B oth pumps are

air-cooled rotary piston type, consisting of two

rotary pistons pumping in parallel. The pumps

attain a low ultimate pressure of less than 10

microns (1 x 10 in. Torr McLeod gauge). The

rugged, simple design ensures dependable servi ce

under the most seve re applications without costly

or complicated maintenance. The ruggedness

of the pump is evi denced by all cast-iron rotary

internals, including the cast-iron sleeve bearings.

The external drive shaft bearing is a sealed

grease packed bearing. The mechanical shaft seal

contains vi ton elastomer, which is suitable for most

chemical as well as high-temperature operations.

PUMP COMPONENTS

All components are easily servi ced and no special

tools are required. The reliable, leak-free shaft seal

requires no adjustment or maintenance. The gas

ballast va lve regulates the va por handling capacity

of the pump, decelerates contamination buildup

in the oil, and quiets the discharge va lve noise

of the pump. The oil separator of the K D pump is

equipped with a mist eliminator to provide ﬁ ltering

of the exhaust, thereby resulting in a cleaner pump

area. The pump speciﬁ cations are shown in Table

4-1 and Table 4-2 on page 7.
