Extensive Range of Pump Models & Configurations
20 basic models of pumps are available in Vertical, Horizontal, Submersible and Multi-Stage versions, for a total of more than 3,000 different custom designs and configurations.
Capacities range from 1 to 2000 m3/h.
Head for single-stage pumps can reach 90 m (295 ft) in the Hardalloy PEMO versions.
All shafts, bases and bearings are over-sized to extend pump life. Complete pump packages are compact, with an industrial grade design.
IMPELLERS
Open Type:
typically made of a metal core coated with a thick layer of various types of rubber.
Metal Type: Hardalloy PEMO (750-800 HB), AISI, Hastelloy C.
Additional metallurgies available as required.

CASINGS
Built with split case design.
Made mostly of cast iron. Some models are available in Hardalloy PEMO, stainless steel, Hastelloy or other metals.
For rubber-lined versions, the interior is protected with vulcanised or separable lining with different compositions depending on the properties of the slurries.

JOLLY SERIES
- Designed for heavy duty slurry and/or acid applications.
- The JOLLY Series slurry pumps are custom built to customer specifications.
- The shaft is always supported above the baseplate by two bearings inside the base.
- The pump-motor coupling is an elastic joint or V-belt.
- The maximum length of the pump under the base can reach 4-5 meters (13-16 ft).
- Using a sleeve bushing as the sealing system, the JOLLY Series slurry pumps cannot run dry under a certain level.
- Capacities from 5 to 1500 m3/h (22 to 6,613 gpm).
- Maximum discharge pressure from 6 to 7 bar (88 to 103 psi).


MEC SERIES
- Designed for heavy duty slurry and/or acid applications.
- The MEC Series only has direct transmission by means of an elastic joint. There is always a metallic structure around the motor with a lifting eyebolt at the top.
- Lengths under the bases are standard and do not exceed 2 meters (7 ft).
- Using a sleeve bushing as the sealing system, the MEC Series slurry pumps cannot run dry under a certain level.
- Capacities from 5 to 1500 m3/h (22 to 6,613 gpm).
- Maximum available pressure from 6 to 7 bar (88 to 103 psi).
AUS SERIES
- Designed for heavy duty slurry and/or acid applications.
- The AUS Series slurry pumps can run dry since there is no mechanical seal.
- Mechanically speaking these slurry pumps are the same as the JOLLY series, but the maximum length of the AUS Series pump under the base seldom exceeds 2 meters (7 ft).
- Usually the fluid inlet is above the casing but in some versions it is also near the bottom (double sided impellers).
- The AUS Series slurry pumps can be installed inside or outside tanks.
- Capacities from 5 to 1500 m3/h (22 to 6,613 gpm).
- Maximum available pressure from 6 to 7 bar (88 to 103 psi).

AO/TI and AO/TD series
- Designed for heavy duty slurry and/or acid applications.
- These are end suction slurry pumps with single or double mechanical seals.
- Capacities from 1 to 1500 m3/h (5 to 6613 gpm).
- Usually maximum discharge pressure should not exceed 3 bar or 43 psi.


AO/AB SERIES
- Designed for slurries and/or acid applications.
- The heart of the PEMO product line, the AO/AB Series pumps are truly unique. Due to the side inlet, the maximum pressure the mechanical seal will see is the fluid inlet pressure, greatly increasing life of the seal.
- When pumping acid liquids, the shaft and the mechanical seal housing can be made of special alloys.
- Maximum particle size is 2 mm though this is dependent on the specific application.
- Capacities from 1 to 900 m3/h (5 to 3,968 gpm).
- Maximum discharge head is 90 m (295 ft) in the Hardalloy PEMO design.
- The PEMO submersible slurry pumps are designed for heavy duty slurry applications.
- High efficiency motor (class IE3) with power ranging from 1 to 100 hp, and speeds from 735 to 3,500 rpm (50 and 60 Hz).
- Standard capacities up to 700 m3/h (3,082 gpm).
- Maximum pressure up to 7 bar (103 psi).
- Double mechanical seals, silica carbide or widia wear rings, oil lubricated.
- Radial bearings, life lubricated and maintenance free, are made to deliver long-life.
- All PEMO Submersible slurry pumps are provided with thermal probe (for the control of motor temperature), and two oil level probe (for slurry leak detection inside the oil chamber).
- The Pemo Submersible slurry pumps all are sold with an electric device for the analysis of the signals from the thermal probes.
- Optional agitator, mechanical and/or hydraulic type.

AO/AB/DC SERIES (double stage versions)
- Designed for slurries and/or acid applications.
- The AO/AB/DC Series is the perfect solution for filter press feed or slurry transfer.
- When pumping acid liquids, the shaft and the mechanical seal housing can be made of special alloys.
- Maximum particle size is 1 mm, though this is dependent on the specific application.
- Capacities from 5 a 900 m3/h (22 to 2,645 gpm).
- The maximum head for some Hardalloy versions is 210 m/H2O.

SUITABLE FOR:
- Applications under head
- Abrasive liquids
- Acid liquids even with solids in suspension
- Operating temperature up to 90 °C
TYPES OF SEALING:
Mechanical seal with front rings double flushed or with permanent lubrication.
MINIMUM MAINTENANCE
Pump/motor coupling:
- By means of pulleys and V-belts
- By means of elastic coaxial joint
These are AO/AB slurry pumps but with two bodies installed on the same shaft so that, working in series, high pressures (up to 12/15 atm) can be obtained, particularly suitable for feeding filters for high pressing.
The Triple Stage PEMO PUMPS, are used with pressures up to 24 bar, have been developed to work 24 h / day in the Ceramic Industry to power Spray Dryers, and today they are also successfully used for new applications of filter presses (bentonite, kaolin , sewage, etc.).
