Temperature Guide & Pump Code Matrix
Caution - Operating temperature limitations are as follows:
Materials
Buna-n - General purpose, oil resistant. Shows good solvent, oil, water and hydraulic fluid resistance. Should not
be used with highly polar solvents like acetone and MEK, ozone, chlorinated hydrocarbons and nitro hydrocarbons.
EPDM - Shows very good water and chemical resistance. Has poor resistance to oils and solvents, but is fair on
ketones and alcohols.
Neoprene - All purpose. Resistant to vegetable oil. Generally not affected by moderate chemicals, fats greases
and many oils and solvents. Generally attacked by strong oxidising acids, ketones, esters, nitro hydro carbons and chlorinated aromatic hydrocarbons.
Santoprene® - Injection moulded thermoplastic elastomer with no fabric layer. Long mechanical flex life.
Excellent abrasion resistance.
PTFE - Chemically inert, virtually impervious. Very few chemicals are known to react chemically with PTFE :
molten alkali metals, turbulent liquid or gaseous fluorine and a few fluoro-chemicals such as chlorine trifluoride or oxygen difluoride which readily liberate free fluorine at elevated temperatures.
Viton® - Shows good resistance to a wide range of oils and solvents : especially all alphatic, aromatic and
halogenated hydrocarbons, acids, animal and vegetable oils.
Polypropylene - High strength, light weight, corrosion resistant polyolefin which easily withstands most chemi-
cals, with no known solvent at room temperature.

Trouble Shooting Guide & Technical Data
TROUBLE SHOOTING GUIDE
NOTE :- Check all solutions before dismantling the pump.
PROBLEM CAUSE SOLUTION
Pump will not start Air valve assembly malfunction/Seizure
Erratic flow Diaphragm failure on one side.
Pump strokes but will not discharge
Fluid discharged from air exhaust
Intermittent stroke rate Over lubrication
Obstructed fluid line. Obstructed diaphragm chamber. Diaphragm failure causing fluid & excessive air to be expelled through the exhaust. Diaphragm seal failure. Air valve system malfunction. Air connected to exhaust.
Valve ball not seating. Suction leakage. Diaphragm failure causing fluid & excessive air to be expelled through the exhaust. Diaphragm seal failure. Air valve system malfunction.
Excessive suction lift. Suction line leakage. Valve ball not seating correctly or damaged. Suction line or strainer clogged. Diaphragm failure.
Diaphragm Failure. Loose frontplate.
Diaphragm shaft seal failure. Air valve system malfunction. Valve ball not seating / partially obstructed.
Check carrier for freedom of movement. ­Clean, oil & replace. Clean line or increase line size. Remove obstruction. Replace diaphragm.
Replace shaft seals. Check all seals in valve chest assembly. Re-connect to air inlet.
Replace diaphragm. Check and remove obstruction. Check and correct. Replace diaphragm.
Replace shaft seals. Check all seals in valve chest assembly.
Shorten suction line. Check and correct. Check and remove obstruction / replace. Clear. Replace diaphragm.
Replace diaphragm. Re-Torque to manual specifications.
Shut-down pump. Remove air connection into pump & introduce a small quantity of de­greasing agent into air valve and replace line. Run pump until clear. Replace seals. Check all seals in valve chest assembly. Clear obstruction.
