Settima Screw pumps

The company Settima Meccanica has been producing screw pumps since 1978 and has become one of the leading European manufacturers. It is an independent, medium-sized company that is run in the second generation. An extensive and flexible range of screw pumps is produced. Settima is DIN / ISO 9001 certified and has ATEX certification for the SMT16B types. The SMT16B industrial pump is based in many ways on the mass production of the elevator pump and is a quiet and economical alternative.

The main applications are: power hydraulics, gear lubrication, cooling systems, test bench construction, oil burners, shipbuilding.

Selection of the pressure level

SMT 16B	The cost-effective pump for almost all applications with pressures up to 40 bar, delivery rates 4 to 3200 liters / minute.

SMT	For operating pressures up to 80 bar, delivery volumes up to 1220 liters / minute.

SMT..SN	The ideal pump for high viscosities and air proportions, for pressures up to 50 bar, for example: gear oil

SMT 8B	An inexpensive alternative for mineral oil and pressures up to 15 bar, delivery volumes 17 to 155 liters / minute

or choose a configuration for

hydraulic oil , transmission oil , coolant or Petrol/Diesel

drive selection

Select the option for the drive from the following table. Depending on the pump size, you can choose between a drive shaft for bellhousing attachment and a hollow shaft (AC) for direct attachment to the standard electric motor. For the shaft version there is the option of mechanical seal TM31Z32 (hydraulic oil), TMZ32Y1 (petrol, diesel) and TMK22U31 (cooling lubricant). With the hollow shaft version, you also select the position of the leakage connection.

option	shafts-ø	shaft length	flange-ø
-	19 mm	36 mm	125 mm
TM31Z32	19 mm	36 mm	125 mm
AC14B14	14 mm	Hollow shaft	105 mm
AC14B5	14 mm	Hollow shaft	160 mm
AC19B14	19 mm	Hollow shaft	120 mm
AC19B5	19 mm	Hollow shaft	200 mm

The pump is clockwise as standard. Upon special request, the pump can also be produced in a counterclockwise version, but this involves considerable additional costs and a longer delivery time. If you need a left-hand rotating pump, please confirm here:Yes, the pump should rotate counterclockwise.

The following pictures show from the left: AC (up to GR70), Welle, TM.

casing

choose the housing material and the surface treatment and depending on the pump size possible connection variants.

default material aluminum
G  Gray cast iron housing, drive flange and aluminum suction flange
A  Housing made of chrome-nickel steel, drive flange and suction flange aluminum
KA  Housing made of hardened chrome-nickel steel, drive flange and suction flange aluminum
GD CS  Gray cast iron housing, drive flange and aluminum suction flange, design for coolant

OX  Aluminum parts hard anodised

pressure relief valve

You can get the pumps with an internal pressure relief valve (RF1, RF2, RF3), permanently set to 5, 10 or 15 bar. An externally adjustable pressure relief valve (RP) for pressures of up to 25 bar is also available. The RF version is available with all suction variants, the RP version only with the standard suction flange.

without
RF1  Internal pressure relief valve permanently set to 5 bar
RF2  Internal pressure relief valve permanently set to 10 bar
RF3  Internal pressure relief valve permanently set to 15 bar
RP  externally adjustable to 5-25 bar pressure relief valve

suction

choose axial or radial suction, suction strainer and other options regarding the suction connection.

The standard suction connection can be mounted in 4 positions (no details = T1)

Attention: In the version with externally adjustable DBV, the position cannot be changed afterwards!

The suction connections AX, AL, SMIT cannot be combined with the externally adjustable pressure relief valve.

Seals

The pumps are available with seals made of NBR, Viton, PTFE and EPDM

Our repair kits contain all the required seals, the ball bearing, the feather key and a protective shaft sleeve to avoid costly reworking or replacement of the shaft and to ensure that the shaft sealing ring functions properly.
