Special design feature and bearing and shaft  seal:

Code	Description of design				Usage
U12.1	Internal ball bearing and mechanical seal.				Pumping medium has better lubricity and the temperature is ≤80ºC
K2	External bearing and packing seal.				Pumping medium has less lubricity,high viscosity and temperature ≤150ºC.
E6.7	External ball bearing and packing seal				Pumping medium has less lubricity and temperature≤150 ºC

Casing:

Code:		Description
No Mark		Standard pump casing,used to pump lubricating liquid with good fluidity.
Y		1.Casing with jacket for steam or heated transfer oil to heat up the medium,used to pump the medium with higher viscosity or less fluidity. highest temperature ≤280 ºC 2. See SHN…E…Y Welding Temperature Structure Three-spindle Screw Pump for details.

MATERIAL CODE:

Material code	Casing		Insert	Using range
Wo	HT200 Cast iron		HT200 Cast iron	Used to pump the medium (such as fuel oil)with better less lubricity and suitable viscosity at lower pressure.
W1	HT200 Cast iron		Special modular cast iron	Used to pump the medium (such as fuel oil)with less lubricity and suitable viscosity at lower pressure.
W2	HT200 Cast iron		ZL109 Cast AL	Used to pump the medium (such as lubricant oil)with better less lubricity and suitable viscosity at lower pressure.
W3	QT450-10 Nodular cast iron		ZL109 Cast AL	Used in particular case (such as marine pump)to pump the medium (such as lubricantoil)with better lubricity and suitable viscosity at lowerpressure.
W5	QT450-10 cast iron		Special modular cast iron	Used in particular case (such as marine pump)to pump the medium with less lubricity and suitable viscosity (such as fuel oil)at lower pressure.
W21	HT200 Cast iron		ZCuSn5Pb5Zn5 Special bronze	Used to pump the medium with less lubricity and lower viscosity,such as heavy oil and fuel oil at higher pressure.
W23	QT450-10 Nodular cast iron		ZCuSn5Pb5Zn5 Special bronze	Used in particular case (such as marine pump)to pump the medium with less lubricity and lower viscosity,such as heavy oil and fuel oil at higher pressure.

Performance data:
The three-spindle screw pump are sutable for pumping various kinds of noncorrosive oil without contents of solid grains and liquidssimilar to lubricating oils, The viscosity of mediums to be conveyed range from 1.2 to 100"E3.0 to 10000 cSt , liquid with a higherviscosity could also be pumped after heating up to lowering down the viscosity.
The flow range is 0.2--400 m?/h, and the maximur working pressure is 40 bar, The highest temperature is 280C.

Features:
For the handing of oil and medium with lubricating properties.
Application:
In heating techniques as fuel oil injection, fuel supply and transfer pumps.
in the Machining industry as hydraulic and telemotor pumps.
in the chemical and food industry as cargo transfer or supply pumps.
In the marine field as transfer, booster, fuel oil pumps as well for ship hydraulicsModel code of screw pump of SN series.
