* PATENT PENDING

Below is a list of questions regarding the type of liquid you will be pumping. Answer as many as possible to help Henry help you. You can always contact PumpBiz via our Contact Us page or by calling 1.800.PUMPBIZ (786-7249)

1. WHAT IS THE LIQUID'S FLOW RATE? (GPM)

For help with unit conversion, please see our conversion page.

2. WHAT IS THE LIQUID'S REQUIRED DISCHARGE PRESSURE? (PSI)

Include piping friction losses, height liquid is to be pumped to, and other factors. See FAQ for further info.

PSI=FT x sp.gr. / 2.31
[sp.gr. Water = 1]

3. HOW THICK IS THE LIQUID?

Check the button above the best description of your liquid's viscosity at 70°F

Thin							Thick
[ Water ] 1.0 cP 31 SSU	[ Milk ] 3.2 cP 40 SSU	[ Cream ] 16.5 cP 100 SSU	[ Veg. Oil ] 34.6 cP 200 SSU	[ SAE 10 oil ] 88.0 cP 500 SSU	[ SAE 30 oil ] 352.0 cP 2000 SSU	[ Glycerine ] 880.0 cP 5000 SSU	[ Catsup ] 3000.0 cP 20000 SSU +

4. HOW HOT IS THE LIQUID?

Check the button above the temperature of the liquid you'll be pumping.

Freezing	Ambient	Boiling
0° C 32° F	20° C 68° F	100° C 212 ° F

5. IS THE LIQUID CORROSIVE?

Check the button above the best description of your liquid's pH.
This does not indicate Chemical Resistance. See Chem Res Chart

Acid	Mild Acid		Neutral	Mild Caustic		Caustic
pH: 0	pH: 4	pH: 6	pH: 7	pH: 8	pH: 10	pH: 14
[sulfuric]	[vinegar or beer]		[distilled water]	[sea water]		[lye]

6. WHAT IS THE PERCENTAGE OF SUSPENDED SOLIDS IN THE LIQUID?

Check the button above the closest percentage.


0%	5%	10%	25%+

7. WHAT IS THE AVERAGE SIZE OF SUSPENDED PARTICLES?

Check the button above the closest size. This does not take into account abrasiveness. Sizes pictured here are relative, but not necessarily accurate. (if none, do not select)


[pinpoint] .04"/100u	[sand] .1"/300u	[fine gravel] .3"	[course gravel] 1"	[golf ball] 1.7"	[lime] 2"

8. HARDNESS?

Check the button above the best description of the solid particles in the liquid. (if none, do not select)

Soft	Medium Hard	Hard	Very Hard
MOH 1 talc plastics	MOH 3 calcite bronze	MOH 5 apatite cast iron	MOH 7+ quartz white irons

9. WHAT IS THE SUCTION CONDITION?

Check the button above the best description of how liquid will enter the pump.

Self-Priming pump situated above liquid, lifting it up through a pipe	Flooded Suction pump situated below liquid level
Sump liquid pump below ground, motor typically above ground	Submersible pump and motor below liquid level

10. WHAT IS THE FLASHPOINT OF THE FLUID?

Check the button above the liquid that best represents the flash point properties of the fluid you need to pump. Also keep in mind the operating atmosphere.

CAUTION: Explosion-proof equipment will be required as dictated by the fluid and/or the operating atmosphere. For flammability please consult the MSDS and your safety officer.

Nonflammable	Flammable
[water]	[ammonia]	[acetone]	[alcohol]	[diesel fuel]	[ethylether]
		Class I, Gp C/D and Class II, Gp F/G
