Product Description
Houttuin 216 Series Pump -
Installation, Operation & Maintenance Manual 21
Seal Chamber
– The seal chamber(s) are under suction pressure only. The 216.40 pump has
four seal chambers. The 216.10 has one seal chamber. They are designed to accommodate
standard single seals in a component configuration. The standard API 682 seal plan provided
is 03.
Bearing Brackets
– Bearing bracket are round type with rigid ribs to withstand greater torsional
load. Bearing bracket are sealed off from the environment by lip seal. Bearing brackets are
isolated and lubricated to protect the bearings. The brackets may be furnished with provisions
for temperature and/or vibration sensors.
Timing Gears
– Timing gears are used to transmit power from the drive to the idler shaft and
to prevent metal contact between the meshed, rotating screws. The "timing" or placement of
the gears on the shaft prevents rotational contact of the pumping screws. This clearance
between the pumping screws relates to extended pump life and higher, average efficiency over
the life of the pump. Spur gear are used for transmission. For the 216.40, the gears are oil
lubricated by means of a self-contained system and are sealed off from the environment by lip
seals. For the 216.10, the gears are lubricated by the pumped product. The gears are of steel
construction.
Bearings
– Radial loading is handled at four locations by heavy-duty rolling element bearings
that are sized to handle maximum loads. For the 216.40, the bearings are oil lubricated at gear
side and either grease or oil lubricated at motor side and sealed off from the pumped fluid by
lip seals. For the 216.40, all bearings are lubricated by the pumped product. The pump is hydro
dynamically balanced, so axial loading is eliminated.
Baseplate
The fabricated steel baseplate supports the pump, driver, and accessories in accordance with
CIRCOR standards or API-676 latest Edition requirements depending on application.
Direction of rotation
The direction of rotation is normally clockwise when viewed look at the drive end of the pump.
The direction of rotation furnished on a specific order should be verified by checking the pump
GA or outline drawing or the direction of rotation arrow affixed to the pump.
